I can create 14.04 VM with Parallels 9 (on OSX 10.9.2) just fine. However, once I install Parallels Tool, the launch and menu bars disappear. There's still some functionality, e.g. I can create a folder and click on it to open the Ubuntu equivalent of OS X Finder (clearly I don't know the former very well). But overall I'm severely limited (e.g. most application windows never appear).
I've looked through posts mentioning similar issues on earlier version of Parallels/Ubuntu/OSX, but none of the tips mentioned has worked for me. Any help here is much appreciated.
