that slows down opening of programs
-----Original Message-----
When clicking a shortcut on my desktop or the quick
launch bar, the program
sometimes take over a minute to open. This doesn't
happen every time (say
one in four). Can anyone offer any advice.
Thanks in advance for any help. (happens on all
programs, not just the same
one)

Win xp pro, 1000hz processor, 512m ram
