I'm using VW 2013 with the service pack 3 installed, so I think I'm up to date. I'm using it on a late-2012 iMac, 27 inch, 3.4 GHZ Intel Core i7 with 16GB of 1600Mhz DDR3 RAM. The video card is a ridiculously wordy NVIDIA GForce GTX 675MX with 1024mb (or 1GB) of VRAM. I'm using OS 10.8.3, which I think is the latest version. Now that that's out of the way, here is what's happening:
From time to time, I'll drag an object, but it will not go. The image stays where it started. If, however, I do a "select all" the object's handles appear in the seemingly empty place where it should have been after the drag. The image I can still see cannot be selected. Secondly, sometimes a wall (or anything else, 2D or 3D) will become discontinuous and pick up somewhere below where it should be. Again, if I do a "select all" the object handle's appear in the empty space where the wall was.
These are two examples of what is happening. I think I have a powerful enough video card and computer. If something is wrong with the card, however, I'd like to take the iMac in while it is still under warranty. Has anyone seen this type (or similar) video scrambling of the image. Thanks in advance for any help.
