The biggest pain in the ass issue I've came across (which is peanuts by comparison to some of the issues with other os's) is how NO browser operates correctly with photobucket. You have about a 50% chance of uploading there, and if you try to watch a photobucket hosted video, the browser WILL crash. I can verify this with Firefox, Opera, Chrome, Konqueror (Kubuntu), and a few others I can't recall ATM.
10.04 MAY have corrected that, but I now it's been an issue with 9.04, and 9.10 (Jaunty, and Karmic).
Jorsher, do you know of a fix for this issue? I've done ALOT of searching, but all I can come up with is "oh well, it's an issue, deal with it".
