Brian, I was, and am, somewhat disappointed in Wnsoft and I'm afraid I got a little snippy with you because of that, and I apologize. My only experience with 64 bit is Photoshop CS4 and it runs flawlessly. I'm still disappointed with Wnsoft. I just use PTE for a few projects a year, since 2002, as a hobby and had hoped to continue. However, there was very limited response from Igor or anyone else except for the thread he started about problems with Win7. The thing is, that I'm not trying to access the full power and potential of PTE. All I want to do is burn a DVD. Although I'm grateful my money was refunded, I would rather have a functioning program for my enjoyment. I was both surprised and disappointed that they apparently gave up so quickly.
