[Lazarus] Form ordering problem on tiling window manager

[Sven Barth]

Hello together!

I'm using the tiling windows manager Awesome ( 
http://awesome.naquadah.org/ ) on i386-linux-gtk2. I've set up the IDE 
in a way to use a floating layout instead of being tiled (because not 
all windows can be docked yet :( ). This sometimes works ok and I can 
select a different window using Win+k and then the window comes to 
front. This also works if I click the window.
But rather often something happens (I don't know what exactly and I'd 
like to find this out) and then I can click on the window and I use the 
switching window keyboard shortcut all I want and nothing happens. This 
even goes so far that modal dialogs (exception windows, open/save 
dialog) are opened behind(!) all other windows. So I first need to move 
the IDE and other windows out of the way before I can work in that 
dialog. I need to restart the IDE to revert to the original behavior 
again (for a while...).
For now I've only achieved this problem with the IDE, not with a custom 
program. It would be nice if someone had an idea what I could test to 
narrow this problem down (the console output does not print anything 
useful).

Regards,
Sven
