Peter,
in version 0.9x-5 the error message problem is virtually gone. The message still pops up, but disappears again automatically in split second. I can live with that behaviour.
BTW: I followed your instructions with a new Music Root, and that seems to work too - in a way (sometimes I can recreate it, sometimes not - with the same track/picture). Weird.

Thanks, Eric.

Right, version 0.9x-4.
I must admit that I am not sure about 0.9x-3, but if you like I can run a test.
Eric.

Peter,
all my pictures are of type .jpg, and the errormessage occurs for every album or track I play. It happens regardless of the size of the picture (360x360, or 500x500, or larger). 

The exact sequence is:
1) Start XXHE. If a picture of a previous session is still there, the error occurs right away.
2) Using Library, select a track and Play Unattended.
3) While playing, restart XXHE (to resume control) and the error occurs. 

I hope this helps. Eric.
BTW it did not happen with previous versions of XXHE !

Peter,
I am getting the following error message when starting or stopping XXHE:

ShowCoverart
De waarde van 0 is niet geldig voor ImageSize.Height. ImageSize.Height moet tussen 1 en 256 liggen.
Parameternaam: ImageSize

When I click OK, the message disappears. It is not a drama, just a bit annoying.
I set the value for Width of Show Wallpaper equal to 800, this fits nicely to my screen.

I hope this helps,
Eric.

Hello Peter,

Unfortunately, I had to reinstall Vista (and everything else) on my system. Now my XXHE activation code does not seem to work anymore.
How to fix it ?
Note: I did copy a backup of the file XXHighEnd1xx.DAT into the newly created XXHighEnd folder.

Cheers, Eric.

As a workaround to the Questions, after installing XXHE, just run once (as administrator) the program called 'HDI'. It can be found in the XXHE folder.
Cheers, Eric.

Right Peter.
Is it correct that the pointer does not move in Unattended mode ? And that it does move when not in Unattended mode ? 

BTW both processor usage and memory behave very stable now. Almost all the load is taken care of by processor 1. Just very little load goes to processor 2.  I have limited the memory to 600MB and that seems to work fine so far.
Cheers and thanks,
Eric.

Peter,
forget my remarks about the music position, it is resumed at the right position It was an illusion. The rest of my description is right.
Eric.

Okay Peter, let me try again. Here is the sequence of events.
I bring up XXHE while playing Unattended..
I move the cursor with the mouse to the slidebar pointer.
I leftclick the mouse and drag the cursor+pointer 2cm to the right by holding the left mousebutton down. At soon as I start doing this, the music stops.
Now I release the mouse. The pointer jumps to the left (beginning of the slide bar) and the music resumes playing from the point where it was originally interrupted.

If I perform the same operation not in Unattended mode, the music starts from the new location (instead of the original one). Just like I wanted it do do. It follows my intuition.

It feels like bringing up XXHE takes a snapshot of the position but without really transfering control to the pointer/slidebar. If I leave the newly brought-up XXHE open until the end of the playlist, another window with XXHE appears at the closing time. So I end up with 2 copies in that case.

Cheers,
Eric.   

Peter,
the situation occurs when I play vanilla WAV files (I haven't tested CUE files yet).
What happens if I reopen XXHE during Unattended playback is that the pointer in the slidebar shows the current position of the file playing, however the pointer is not moving.. When I move the pointer manually, it automatically resumes its start position. And after a short pause, the music continues where it stopped.
NOTE I was monitoring Windows Task Management - Physical Memory. It is showing a dip in memory allocation at the time of this event.
I hope this helps.
Cheers, Eric.

Another observation in 09w-5. Perhaps memory management related as well ?
When I play in unattended mode and I open XXHE again to move the progress slidebar at the bottom to a new position withing the track, l experience unexpected behaviour. It used to work quite comfortable in previous versions.
Cheers, Eric.

With 09w-5, I observe the following behaviour. During playback of a (pretty long) album, it occurs to me that the physical memory used is increasing steadily until it reaches over 90%. Subsequently Engine3 crashes.
In addition I notice that occasionally between 2 tracks a very short moment of another track is played.
I hope that this feedback helps in finding and repairing the cause of the error.
BTW, SQ is excellent !
Eric.     

Thanks Peter,
running HDI.exe once as administrator helps.
I hope that someday this workaround won't be needed anymore.
Cheers, Eric.

Hi Peter,
Every time I start and stop XXHE, a new ChangeWP process is added to the list of running processes. In addition, the wallpaper does not appear. I am on the newest Versions.
Any advise ? 
Cheers, Eric.

Sorry for the confusion Peter,
I just found out that my assumption was wrong. My error was that I did NOT copy 0.9v-6 OVER 0.9v-5, but I replaced it. I changed it and everything works again.
Eric.
