I have wasted hours trying to resolve an issue with Parallels Control Center crashing repeatedly with PD9, OSX Mavericks and Win 8.1. This happens every time upon boot after responding to the Windows security prompt to allow Parallels Control Center to run. As a result of this host<->guest copy/paste and other functions that were previously working are now in-operational. A problem report with ID number 30121603 and full details was sent to Parallels. I would appreciate any assistance in resolving this. Thanks!
