i had this problem before when i first started wrking on the updater. it has to do with VB being rather stupid. i thought i had fixed it using some timers to work around the problem, and it seemed to be working for everyone, but apparently soemthing about your system makes it not want to work. i appologize and wish i could do something about it, but there is really nothing i can do, if you are familiar with visual basic .net coding, you are welcome to get my source code and take a stab at trying to fix it yourself, its on sourceforge.net @
