What bugs have you found in OS 2.5 firmware?

[llamastorm]

I have a new Virus that I have so far been playing with without using Virus Control.

I wanted to know how buggy the current firmware was and whether anyone else has seen problems, so that I can help understand whether I should be expecting this synth to have bugs or not I love the sound but would be a lot less stressed out if I knew these were things that the Virus was expected to do rather than my Virus possibly being broken. Right now, it's hard to tell.

Has anyone seen a somewhat hard to reproduce bug where they are playing the keyboard and while notes continue to come out, the controls stop working and you have to cycle the power? How about the same with the screen becoming white with no text, but still producing audio, with inactive controls?

Are there any other hardware (non Virus Control) bugs you have encountered with this OS, and if so, what are they? What conditions generally cause problems?

Thanks!
