OS 2.7.5 bug?
 

Hi on the whole the update went well but I seem to be having a problem when closing a host after having played the Ti Control (it has happened with several - Sonar, Reaper, Cantabile) that I can't get the Virus hardware to make a sound any more until I reboot the Ti. Looks like the driver is not being fully released by the hosts but it was working fine in them before. Anyone else had this happen? This on Windows XP Pro sp3 - Dualcore Dell laptop

No one else had this?

Nope I haven't noticed this problem, but it seems that the 2.7.5 OS introduced a number of problems I didn't have with 2.7.3 (arps going out of sync when using the knobs on the Snow etc.).

Is there a way to downgrade OS versions?

Not sure. I find on the whole the update has increased performance for me but this is a bit annoying (though not a showstopper).
