Could you please go to the preferences>performance> uncheck "Use graphics processor".
Is your watermark a png file?
Also did you try with a different watermark?
Thank you for taking the time to help me! I think I may have fixed some of the issues with a bit more trial and error.
As for the graphics processor, it was already unchecked. So, I checked it to see if that made a difference. Well, it did. The sliders work correctly now. However, advancing the pictures takes a bit longer than normal. The photos are already rendered at a 1 to 1 ratio and should forward faster. But with each advance, I have to wait for the panels to refresh. However, the problem of not being able to move around within a picture with the hand curser is gone. It appears that by adding the graphics processor, that issue was corrected. Just so you know, I have an ATI FirePro V (FireGL V) Graphics Adapter. See the particulars below.
As for the watermark...
Yes, it is a png. And yes I did try a different watermark that worked. I went ahead and deleted the watermark I was trying to work with, and rebuilt it fresh. Perhaps it had gotten corrupted or something, because the new one works fine.
Again, thanks so much for getting back to me and being willing to troubleshoot this thing. I get so frustrated!
