Michel,

OK, this is working now.. I'm not sure what fixed it as I am now registered and using the recompiled units, but I think it had to do with needing a refresh after loading the image. Thanks for your support.

Any chance of getting a progress event on the load from file and load from stream? Some files (not many but some) for some reason take longer to load (and its not file size) anyway just when you think its stalled out, they magically appear.
