Hello,

I noticed that in some situations which I can't isolate right now, the picturebox control first seems to clear itself before it draws. In the picturebox_Paint() event, I have a messagebox at the very first line; at the time this messagebox is shown the picturebox is sometimes empty.

I have been trying to figure out why this seems to happen in some situations, but I haven't found it yet. So, is there a situation where the picturebox would first clear itself before redrawing? There's a big chance that I'm doing something stupid, but if there's a logical reason why the picturebox would first clear itself, perhaps I can isolate the problem faster.
