This isn't caused by Morroblivion, and isn't really related to it, but I thought someone on here might have heard of this and know a way to solve it.
Every so often when I'm playing Oblivion, my game is minimized an an 'Active Movie Window' is brought to the forefront of windows. I then have to use Alt + tab to get back into my game. Sometimes I can amass up to three of these annoying buggers. If I close the one that is highlighted, then I can't move when I get back in game. If there are multiple windows up, I can close all but the 'active' active window. When there is more than three in the background, I have a good chance that my game is going to crash.
The active movie window displays what I think are album art from the music in my music folder, even though there are only mp3s in my music folder. I use Better Music, which makes me wonder if that mod is affecting it. Have you guys experienced anything like this?
Thanks

Do you get a few ffdshow
Do you get a few ffdshow (arrow) icons in your taskbar while playing oblivion? If so, you need to fix this by:
go to start>programs>ffdshow>audio decoder configuration. Then highlight "info & debug", on the left side. Near the bottom right corner, make sure "Don't use ffdshow in:" is checked. It should already have explorer.exe in it. Just add oblivion.exe to the box also. Afterwards, it should look like this: explorer.exe;oblivion.exe
ALternately, associate .mp3 (and possible .wav) files with Windows Media Player.This can be done in WMP through Tools>Options>File Types and clicking the check-box (be sure there is a tick-mark present) next to 'MP3 audio file (mp3)' and 'Windows audio file (wav)',then clicking 'OK'.
That may sort your issues out.
