In 50% of the cases when I quit Cubase the main window doesn’t close and the application “hangs”. The only way to get out of it is with ctrl-alt-delete. Even then some part of Cubase stays active disabling the soundcard. The only solution is a reboot. I think it has to do with the release of the audio-driver. Specs:
Intel iCore7 with 12 Gb RAM
Windows 8.1 (also with Windows 8) 64bit
Cubase versions 7.0 to 7.5.20
Audiocard UR44 with latest drivers. I had the same with my M-Audio 410 firewire soundcard
3rd party plugins: No, only Steinberg and KOMPLETE 9
eLc version: Was a little outdated, but upgrading didn’t solve the problem
Compatibility mode: No, set as “run as administrator”
The problem was with my extra MIDI inputs, a M-Audio MidiSport 2x2. The Windows 7 64bit driver seems incompatible with Windows 8.1. When I disconnected the device, I had no more crashes…
