Hello,
My girlfriend has recently noticed one bug - after long period of K-meleon being active (more than a day) she tried to open links/webpages and saw nothing but blank pages (and 'ready' status in status bar). Little did she know that internet connection was all right. I had to open Internet Explorer ;( and it worked
(
K-meleon didn't work even after restarting application. Finally rebooting did its job.
