.JPG only works with the web-enabled desktop, which I've always avoided, and (thankfully) is not enabled by default. Not sure it's even there anymore in XP, since I've always ignored it. 
My example code wasn't tested - I just found several inconsistencies in your original code - compare the two and see what's changed. Seemed like the vines and underbrush were attacking the trees.
I can post our BGI.kix when I get to the office today.
