Rightclick pin manipulation freezes beta26

well title says it all. happened to me all day long, with various patches, if i edited pins by drag+drop with right mouse click. i think most of the time it happened while dragging.

could not reproduce it, but it happened often enough to be really bothersome. there was no exception i could offer here, vvvv just froze on me and had to be removed with killVVVV.bat
