Hi
What version are you using? Using the latest version VP8.35 Pan and Zoom work correctly on an image and also OK if preceeded by a cross fade or followed by a crossfade. The export is also OK.
If you can set up a short project with 3-4 images that demonstrates the problem and then SAVE PORTABLE PROJECT AS
This creates a dated folder with all the necessary files in for us to reconstruct your project and see what might be going wrong. Upload the folder (or all the contents) to Dropbox (or a similar hosting site.) Make it public and post the link here to the forum and we can download it and take a look. Instructions.......
