I have a PC desktop with the following configuration: MS Vista Ultimate, SP2 4 GB Ram Intel Core2 Duo processor E7300, 2.67 GH nVidia GeForce 7300SE/7200GS with G72 3d Accelerator Dual monitors, Acer AL2216W and Viewsonic VP 191b My problem is that any version of PTE higher than 5.5 does not work. I have 5.6, 6.02 and 6.5. When I choose a set of images and hit Preview, the computer hangs. When I hit Create, an exe file is created and saved. It does not run - gives a black screen and I have to use the Task Manager to exit. I also have dual boot on the computer so I went into XP and tried it there with essentially the same results. The exe files created DO work on another PC just fine. I therefore believe that my problem is related to my video system in some way and hope someone out there has a clue or two for me. Thanks in advance, Ken
