When you say it vibrates at times, you mean that the blink rate is studdered or so?

At work I have a PIII 550 w/327 Mbs of RAM and it buggs me like you wouldn't
believe. Almost everytime that I am replying I loose my cursor because of the
resource drain from all the animated smilies, the big Ad in the upper right
corner of the page, etc. Even at home now with my P4 2.8 dual channel 1
Gig DDR RAM even takes a hit by the new MS Speed ad and the Sprint ads.

It blinks sometimes and sometimes not - dont know where it is so I have to
click in the reply box to refresh the cursor position.

I think the new version of the Forum software is more resource intensive, but
its worth it.
