Layout taking more space than necessary...

Question

Hi folks...my applet has two panels inside it arranged in a flowlayout. The first panel is a 5 row x 1 col gridlayout, and the second is working fine. The problem with the first one is that that it is taking more space than necessary and going out the bottom of the applet. Now if I do this in appletviewer, resizing the window by a few pixels will make it relayout the panel and everything looks fine, but of course you can't ask people to do that =) What's the problem here? I've tried validating both the applet and the problem panel, and tried invalidating it first. Any ideas? thanks!

Here is the first half of it...it has all the relevant info. I took out the validate stuff 'cause it wasn't helping.
