I opened a 1.5 project in 2.0. Hit CTRIL + ALT + SPACE to preview the project. However all of the visuals are hanging off the bottom of the preview window, you can see about 50 pixels worth of the menu or video. Same thing happens if trying to play a timeline. I can navigate okay, knowing I can hit the one button on the first menu to play a video, and I hear the sound, but no picture.
This is at 1280x1024 on a dual display matrox video card.
I lowered the display resolution but same thing happens.
I also get the "an abnormal condition has been detected." message upon opening the existing 1.5 project.
