Ive had this problem for years but recently its got worse. Everytime someone is invited into a convo im currently in or they leave my computer goes right slow and msn sometimes crashes... but now it does it every convo...

Anyone else had this problem and know how to fix it?

does it still do the same without plus! installed?

If it does, sounds like something you should report to Microsoft about, but it could also be due to a lack of RAM as well, so make sure you have enough RAM to combat that.

SO basically either get more RAM and see if it helps or report it to Microsoft provided that it still happens without plus! installed.

Maybe WLM it's taking too much of your computer and most when there is a group conversation???
Have a try on ReduceMEM by Sypher

The thing is my pc is a gaming pc and has plenty of ram (1GB) and theres nothing running in the background or on startup....

Hmm sounding more like something to report to Microsoft as well....just check if it still does the same thing without Plus! installed. If it still does the same thing, definately report it to Microsoft. If it doesn't happen then we'll see what else we can come up with.

How would i contact microsoft about my problem?
