Yep. I lost some wu's after installing it, on both the Mac and the PC. Also, it would connect to server but kept coming back with 'no work from server' when they they had bundles of work. They (sah) have been having some drawn out server connection problems, and I thought it might be that. I re-booted both machines and that seems to have cleared it, and its running ok. So I'm not sure what's up.
