When you view lots of pictures while having an instance of k-meleon open, eventually the body of the page will not appear - it will just be white. If you go to another browswer window, that's just white too. Any pages you go to are just white - nothing is being displayed.
I don't know if this is from opening too many browser windows (one for each picture) or just for opening many pictures.
I'm viewing pictures from explorer so each one opens a new browser window. This only occurs when there is one window open throughout the whole process.
If you look in task manager, k-meleon's memory usage increases after every picture, and for me, it usually stops working once it gets to 32 megs (i have a 16 meg memory cache if that matters).
Maybe there's a memory leak or something - i have no idea.
