First, I'd like to say that Version 5 is a fantastic piece of software. WOW. Now, on to the (possible) bug. I have a show created in ver 5.01 (latest download). Works beautifully in WinXP. It has only simple fade effects for all slides. I tried this with hardware acceration on and off, windowed and full screen. In Win98, the main screen comes on, but it's just blank, black screen. If I waggle the mouse, the nav menu appears and I can move to the next slide using the buttons. It's just a cut to the next slide, though, no fade effect as it should be doing. Unless I use the mouse and the nav buttons, the show will just sit there and do nothing. No music is playing (none is in the show), so that isn't interefering with anything. This was a really simple show, just a test. Nothing fancy at all. The computer running Win98 is a Dell with 96meg memory, and 450 mhz PIII processor. ATI Expert98 AGP 2X video card. I guess the question is, should this simple of a show run on the computer configuration I described? I'll be out for the next few hours, so if I don't respond to queries right away, that's why. I'll check back later on. p.s. Ver 4.48 shows always ran fine on the same computer, FWIW. Don -edit- I just remembered something about having to have a particular version of DirectX. I'll have to check that computer when I get back to work tomorrow.
