Hello:
What sites were you on when the lag occured?
Also did you install the memory corruption bug fix i.e.:
http://www.internettablettalk.com/fo...ad.php?t=11824

I have found that the Opera browser has trouble with some pages (especially slow in "optimized view")

I would suggest re-flashing and installing the memory bug fix (download the bug fix to your 2 gig card before re-flashing so you can install it without having to go on-line)

have fun
ben
