I downloaded and installed the most current version, and so far I'm very impressed. I did notice two bugs, however:
1. At one point a frame got so completely stuck to my cursor that I had to log out to fix it. I couldn't figure out how to reproduce this, though. I had the config menu open at the time, and was just moving the frame when it became stuck.
2. I was trying to configure the raid bars for a 10 man raid, but the bars refused to wrap to a new column, no matter what I set them to (even if I told it to only have one frame per column). I couldn't get it to do anything other than the default single column.
