Hi, Sorry, I should have mentioned this in my previous e-mail, but I am running the most recent drivers of the HD4000 graphics card. Furthermore, I'm also running Ubuntu 13.04 (x64) on my current system (dual boot, so no virtual box or anything), and there I experience the exact same thing (maybe even worse). When using the HD4000 card, Caret v5.65 just hangs as soon as I click on the surface or edit voxels. However, when I switch to the Nvidia card, Caret runs fine again. So in my case, the problem occurs both at windows 7 and Ubuntu 13.04. Let me know, if I can be of any further help. Cheers,

Make sure your graphics card driver is up-to-date. It would be nice to know whether that helps any of the three we know experiencing this problem. (Also, whether anyone is seeing it on a platform other than windows.)
