does anyone else get this? it started in 6.5 for me, when working with more than 1 project open at once, or adding instrument tracks, all channel faders will move to the lowest position but the track continues to play as normal… it’s very strange… any idea what the cause of this is?
I guess i sort of just answered my own question! seems to be related to jbridge… 
I had this situation few times in C6.x. Very strange…
This happened to me in 6.5 and now in cubase 7 as well. So far I have not seen any pattern, it just happens sometimes. I don’t use jbridge.
(Im using the 64 bit version of Cubase btw.)
