Windows 7. When I try to use the Windows Explorer to rename a folder on my C: drive, it refuses and says the "folder or file is open in another program". When I look at all the handles on the system (Sysinternals handle.exe), the only process that has a file in that folder open is prl_cc.exe. It's holding on to a seemingly random file in that folder. The file that prl_cc.exe is hanging on to is some random subdirectory deep in the Visual Studio 2008 project; I am trying to rename the top level folder of that project. It's a subdirectory or file that I have never accessed from the Mac - it's bin\x86\blah. VS has surely accessed that file this week, but not lately. Nothing on the Mac side has anything open. This is all on a freshly booted Mac. First thing I did after starting the VM was to run Windows Explorer. The only other thing on Windows is running the diagnostic handle.exe in response to the error message. prl_cc.exe actually has 105 handles, of which about 100 seem random and suspicious. What's going on here? I don't think I had this problem for the last two weeks when I've been using this VM. Now I can't do any work at all and seem to be totally hosed!
