I have absolutely no idea why, but everytime I visit Youtube, when I try to close the tab that I had youtube opened in, it won't close. I can't close th window or that tab, I have to kill the process in the task manager, which is really annoying to have to do. I know that Flash isn't 100% compatible with 64 bit OS's but seriously, I've never heard of this problem before, and never had it myself, in the year that I've been using x64. Has anyone else here had this problem and know how to fix it? Btw, when I try to close it it gives me the Windows "default beep" sound.
