Switching between parts in multi mode
 

I have a Virus Rack Classic. When i'm in multi mode and i'm looking at, for example, part 1, and I want to switch to part 2 using the cursor keys sometimes it just wont happen. Pressing the cursor key will not move me between parts. I think this happens more often when i've just switched on the Virus, but i'm not sure it's consistent.

I manageto temporarily fix: repeated pressing the multi button and then trying again to move to the next part seems to work! Then the problem happens again. F##k doing that all the time!

Just wandered if anyone else has had this problem?
