window disappear

[Emanuele]

Hi all,

it's about 1 year that I'm using Dexpot and I think that it's great!!

Unfortunately, in the last period I noticed a strange effect: when an application run at 100% for a medium/long period (1 hour more or less) and I'm working around all the other desktops, at one point it simply disappear...
No warnings, no error messages, I can see the process working on windows task manager, but not the window...

I searched the forum, but I didn't find anything related, do you have any advice?
Thank you in advance!

EDIT:I forgot to say that usually I set process priority to "subnormal".

Regards,
Emanuele.
