Resume from minimized - bug (1 Viewer)

[Swede]

Resume from minimized is very buggy now. Sometimes a black screen, sometimes white, and sometimes transparent (you see desktop, but cannot click anything until you do alt/F4 to minimize MP again)

When minimized, the log gets extremely full of shit like this:
2008-12-19 11:30:40.164459 [ERROR][MPMain]: Exception : System.NullReferenceException: Object reference not set to an instance of an object.

...and so on for several MB - but not always.

Hi,

Does this happen with the default Blue3 skin?

Presumably you are in windowed mode before minimising? A detailed step by step description of the problem will help the team reproduce it.

Best wishes,

Mark

Vista PC
I only use Fullscreen
Same problem in all skins
I have the "Minimize to tray at exit" option on
Press Alt-F4 or the exit button and MP will minimize to tray. (now check log activity witch sometimes is huge)
Right click the MP icon in tray and resume, or double click the icon.
Do this a few times and I hope you will reproduce the problem

Maybe only a Vista problem. I cannot reproduce this in my XP client.

Regards,
Swede

I have the same problem with MP1. Only on the Vista Ultimate PC using Blue3 skin. It is not happen on my XP machine ?
It doesn´t matter if settings are full screen mode or not
It seems to happen randomly. However I feel like it is more likely to happend after a recording ?

hi Swede

this looks like a problem I'm trying to resolve. But instead of getting it when resuming from minimized I get it when resuming from standby, maybe there are similarities between the two scenarios? I get the following error message in mp log when it happens:

2009-01-04 18:07:50.213968 [Info.][MPMain]: Main: Windows has resumed from hibernate mode
2009-01-04 18:07:51.335580 [Info.][MPMain]: Exception ystem.NullReferenceException: Object reference not set to an instance of an object.

at MediaPortal.GUI.Library.GUIGraphicsContext.ResetLa stActivity()

I have described the problem in:
