I'm happy to help fix the code but if the main developer of this code could maybe say a few words about the code and the logic, it would help! (For example, what is the thumb stuff about?)
Thanks,
Emery

Hi,
Again, same source as I posted yesterday (below). If I load a jpeg in
and drag the slider bars, it rescales the window rather than show the
next section of the picture.
If I click beneath where the slider is (so it's on the bar itself), then
the picture moves.
I reserve the right to be wrong, insane or a bit foamy on this. I will
put it into BZ if needs be. Mono was compiled about 20 minutes before
posting this email ( 14:15 BST )
