Thank you, I just downloaded and installed it.
When I save the project, PSD seems to save the .dsk file now whenever I had changed the windows list order before and doesn't save it, when windows list order has remained the same since last saving the project. This seems to be reasonable.
I'll keep an eye on any sort order mess-ups and will let you know about the result.
How does it work with Window-Save Layout? I can't see any timestamp update in the user.prefs nor in .dsk nor in .prj file, when I use that menu option. Where does PSD store its Window Layout and when?
Is it maybe still implemented the same as Project-Save was before, just saving when PSD gets closed?

The "Window Save Layout" is stored in the registry, either when selecting the menu item, or when the application is closed (when the save desktop preference is set).

HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Desktop

Thank for your feedback. I think the original problem can be considered solved now. I haven't had any occurrence of the problem with Version 8.0.1.1504 anymore. I'd suggest you make this release generally available.

Looks like this problem occasionally occurs again in the latest version 8.0.1.1510. It seems to behave like in 8.0.1.1502 again. Please get this fixed soon.

What exactly goes wrong with 8.0.3.1510?

I'd say the description I gave about 8.0.1.1502 on January 22 applies again:

[quote]I still have some random issues regarding messed up windows sort orders. I would guess it happens now in less than 5% of closing pl/sql-developer projects and opening them again. In that case it seems to go back to the former behavior, coming up in a sort order that I sure never had stored the project at any time. I have a feeling that it happens more often when memory gets scarce and lots of other applications are open at the same time.[/quote]

We'll check it out.

Maybe this helps in checking it out: When PSD had crashed before and I open via Crash Recovery the next time, window list items will always come up in an order I never had saved them before.

Okay, thanks.

Please get this fixed soon and once for all! Just two days in a row now when opening my PSD project I had to resort my window list items, because PSD seemed to think it's a good idea to put least recently used items last in windows list again.
