I'm trying to display a list of Bitmaps. The bitmaps are all different sizes.

When I use the following code in a Blackberry that runs OS 4.2, everything is fine. As soon as I use the following code for OS 4.1 (say an 8700), things are all screwed up.

Anybody have any thoughts?

all screwed up like they're wrongly sized or you get compiler or runtime exceptions
