GUI dialog menu throws exception on close of menu

TV-Server Version: 3 May 07 01:22

Windows Version: XP Professional

Causing a GUI Dialog Menu to close (by clicking an option) throws an exception. This is manifested by making the entire GUI unresponsive. The menu disappears, but then no other option can be selected, or highlighted, save for buttons on the top bar; however these do not function when clicked. The close button on the top bar still, however, causes MediaPortal to minimise. Video and audio keeps playing. When MediaPortal is restarted, then it appears that whatever action you tried to take was successful (i.e. ordering MediaPortal to record a programme). The programme simply does not respond to any input after the action is taken. The problem occurs with every menu in MediaPortal. MediaPortal worked fine with revision 11 March 2007.

Hi,
Is this only when using SpinSafe Revolve or does it happen with B2 too?

Regards
Roy

[Roberdin]

When switching to BlueTwo the problem ceases. It only affects SpinSafe Revolve.

[Stor-Anders]

I can confirm this issue with all late SVNs combined with skin Simplify wide.

Any tips how to modify the skin?

I got the same issue with BlackMyst, Aqua and Spinsafe and with BlueTwo everything is fine.

I'm away from homw at the moment so can't look into it myself, but a good place to start would be to look in the blue two folder and check the most recently modified xml files.
I'm guessing there would be a changed XML that deals with menus or OSD's.
Once you find it then check for differences in the same XML in the skin you are using.

If you still run into trouble post back and I may be able to give more info...

[Nox71]

For my part the problem come from the DialogMenu.xml file, i just put the one from BlueTwo and it's working now. The next step would be to find the difference in the two file to fix the one for Aqua. I think that it should be possible to solve the same issue with other skin.
