I recently migrated reaper from to a Win 7 (64 bit) machine. Reaper and WS are both 32 bit. I have found that when playing a track with WS, I often get a massive output level when WS first plays (like +55db) which makes reaper automute. Unfortunatly, when I go to unmute WS, the plugin has crashed.
Like I said, the OS is 64 bit and the DAW (reaper 4.31) and WS are both 32 bit.
The machine is a core i3 laptop with an M-Audio interface.
-edit- : it only happens with projects that have been saved. This never happened on my old system (an old win xp Core Duo system).
