Menu Height Problem
Date: May 08, 2001 07:23PM
With the bitmapped menu plugin enabled in .4 nightly, the menus appear all crunched together... This is obviously because in my display settings I have my menu height set to 15 instead of the standard 18. I don't know what a good work-around for this would be, but something should probably be there... Whether it's clipping the images, resizing them on the fly, or something. Just a thought. (it still works great...)
