We use SVN to back up our documents, and recently it appears that the SolidWorks process "sldShellExtServer.exe" is causing commits to hang.  I understand that this process helps create the thumbnails, and can be somewhat CPU intensive.  Here's the info dump when I have to shut down the TortoiseSVN commit:

I'd prefer to leave the thumbnails enabled (they're helpful in visually tracking down files).  Are there methods to alleviate the CPU strain (if that indeed is the issue)?  Or do I need to shut down this process, and if so, is there a simple way to do so (and how do I turn it back on)?  (I gather it runs independently from SolidWorks, so just quitting SW won't work.)
