I have also problems with 1.07. (directx error when clicking on the first unit) My desktop resolution and SC2 resolution are the same (1600x1200). I uninstalled the game, then reinstalled from CD and applied 1.06 patch and after that it played fine again. I noticed the same error with the unpatched CD-version which was 1.02. (Windows Vista Home Premium, NVidia 8800GTX, Intel quadcore QX6700, 2 GB system memory)
