(Chuckle...) thanks Doody, I will heed your advice when next I take a look at the TE. It's just that life being rather busy, I simply didn't have time to wrestle with what should be the simple process of loading a bitmap file into the TE. I can't see any reason why one shouldn't simply be able to creat a suitable bitmap in a paint program, then use a file browser in the TE to load it in, mess with it in the TE, then save it out. I mean, thet's a fairly fundamental way of doing things in any data-handling program... - especially graphics ones, and that, in effect, is what the TE is. So why is it so flipping awkward? And why does the darned thing fall over rather than just simply winge that I didn't do what it wanted me to do? (Shrugs...)
I'm not goin to let it put me off altogether, but it IS delaying me getting to grips with the TE, because there's several other things calling for my time, so anything that is unecessarily awkward is going straight to the bottom of the priority list!
