For the adventuresome, the new BOINC 7.0.38 is out for testing (Windows only at the moment). I don't even see the release notes yet, but I believe it solves a problem if you are running GPUs on two or more different projects. The queues were not managed quite right in the previous versions, though I was not having any problems with 7.0.36 myself.

But if you have a problem, you will probably need to join their mailing list to get someone to work on it if it is specific to the new version. However, 7.0.38 (64-bit) is working fine for me on Win7.
