I am slightly curious if there was a difference with the latest (0.7.1.2) version over the last (0.7.1.1) because I might have made a mistake putting the changes in that I thought were in. I'm sure they are in 0.7.1.2. If you could please give 0.7.1.2 a shot and let me know, I would totally appreciate it.
If it doesn't work, please email me at firstname.lastname@example.org
the trace.txt file that should be in the same folder you installed VtV to. This will help me to tell if the extensions are getting properly queried.
But, there are two versions of this bug (and scoin I can't remember which one you were encountering). One appears on Unichrome and one on GeForce 6800 and 6600 (I think) cards with the latest NV drivers. The latter has to be fixed I think by NVidia, I applied as a developer but I think they may have ignored it. =) But the first bug I was hoping to have fixed!
Whew! So that's the status. This is still definitely near the top of my list, becuase VtV should probably run OK on unichrome. Thanks everybody!
