Try this:
1. Drag a GIF onto a track (my GIF was 720x576).
2. Select Overlay Options
3. Select Mask/Image Matte.
4. Select the same image as the mask
5. Save the project
Then attempt to re-open the project. Depending on how it feels you either get a File Reading error 20379:1:107, or the editor simply crashes. This reproduces solidly on two machines and with MSP7.3 and MSP8 preview for me. Anyone else experienced this? (I expect you'll say why are you selecting the same image as the Image Matte...)
