i made the quicklaunch into a recycle bin.put the recycle bin and made it into large size.and about the corners thing i was just wondering.i haven't tried.the tweaks i did are using stylish and new glasser addon in firefox to enable aero,changing start menu button,changing logon screen pic manually from regedit,password on boot,password on loading windows,lot of gadgets,making text appear when logon screen appears using regedit (explained most important tweaks) e.t.c.
was gonna enable dream scene using tool but figured out my windows wasn't genuine.will locate key before i use my laptop again.I'll try to check the quick launch thing.thanks!
PS:Tried rebooting,system restore and anti-virus,so guessing problem on my part.man i was relieved when you said it was a quick launch bug!
