If I were you I'd be more worried about PSD crashing all the time

It's not only happening when PSD crashes. A crash just quite certainly messes the windows list order up. That posting was meant as a help for development to sort out this problem.

Again and again I encounter my windows list messed up after restarting PSD. Any idea when this problem will be fixed and my Sisyphus task of having to reorder them manually all the time will cease?

Is there any fix included for this problem in the latest version 8.0.4.1514 ?

No, unfortunately we cannot reproduce any issue with the sort order.

So far I haven't had an issue with it in 8.0.4.1514, I'll let you know if it happens again. If that's the case, would it be feasible to create a diagnostic version that can tell you what exactly goes wrong in my case?

If the problem is reproducible for you, that should be possible.

I'm having the same problem, and I agree that it is annoying, since I have up to 10 Package windows open.

By the look of it, after restarting PLD the windows seem to open in the order in which the were opened/created and not in the last sort order.

Explicitly issuing 'Save Layout' does not help.

At first I thought this may be caused while opening PLD installed on Windows 7 from a virtual XP machine, but installing PLD within the VM gives the same results.

Version 8.0.3.1510

I have just had this problem occur again in the latest PSD version 8.0.4.1514. So I think if developers have no idea what is causing this, we really need a diagnostic version to gather the necessary info for fixing.
To me it seems to really be a memory issue. In the latest occurrence I tried to open a PSD project while lots of applications where already open. It then only managed to open a few of the windows of the PSD project that I tried to open. So then I closed this whole PSD instance again, closed some more applications to free up the required memory for PSD and then tried opening the same PSD project again. Now all my PSD project windows were in wrong order, even though the project was never saved in between.
I guess when memory is scarce PSD, should rather fail to open altogether and never save anything in that status while risking to mess things up. Hope this helps in fixing this problem soon!

In the past I've seen a similar issue where when the system was running low on resources (usually "desktop heap" space) PSD would crash and fail to correctly save preferences, causing preferences to be reset. I haven't seen this problem in a good while, though.
