Usually, it takes a second or less for User Account Control to switch over to
the secure desktop and the same amount of time for it to switch back.
However, whenever I need to provide permission on my computer, the screen
will black out for 3-5 seconds, I get the UAC prompt, and after providing
permission, the screen blacks out again for another 3-5 seconds before
returning to my normal desktop. I honestly have no problem with UAC, but this
unusual delay in brining up the prompt is extremely irritating. On enabling
my computer's guest account, I discovered that the UAC prompt functions
normally on the that account. It is only on my account that it acts slowly.
Any ideas what might be causing this delay? I've spend ages browsing forum
after forum and am still unable to find a solution.
