I'm giving Trish tons of credit for not taking my reply too hard. I was blunt but meant no flame for sure.
Sounds like she took my advise and reset the unit and its doing better.
I'm not using the task killer she talked about either but do have Astro and use it's "Process Manager" to pick through once and a while for GP and kill things. But just because I read on forums how it's a pretty common practice.
All this task killing has me doubtful it's needed and if it is I am disappointed. I have been using computers since the Commodore and can remember how "Windows95" was ridiculously notorious for needing to be restarted to release resources or it would lockup. Then Windows98 got a little better and Vista even better. I run machines with Vista that are Super Stable and hardly ever get restarted.
But I hand build them and hand pick the configurations and software too.
