Because it appears that there are many of us that have this problem I wonder if it could be due to the system used the OS in particular.
So far it seems it is a problem with floating the CV on one of two monitors and undocked. My OS is Windows 8 Pro 64 bit with 8 GB of memory. I have a GTX 550 Ti with 1 GB of on board memory.
One last thing, I don't think it matters what FX is used.
The crash occurs by just clicking on a buss. In my case it seems to happen on the master buss.
Let us see if our setups have anything to do with it.
Thank you.
