Serious Redraw Problems in 0.4
Date: May 11, 2001 07:54PM
I'm noticing that with the new 0.4 release, K-meleon seems to have trouble completely redrawing pages if you have multiple windows open, and are switching between them, and have some other window on top. I don't know if this problem is related to Mozilla or the embed library or what, but it unfortunately makes using the browser nearly impossible, since you have to minimize and restore it so ofter to get it to redraw the display.

This is a mozilla bug, and has already been fixed...this will appear in the (soon to come) nightly builds of .4.1.
