MSN Messenger 7.5 (Build 0306) Problem

Hi,

Thought I may as well update to this new version, I may be thinking that I
wish I never.....

So here's the problem, that maybe someone else has encountered, or maybe its
just me?

Completely removed previous version of msn, (all reg entries etc removed
also, just in case!)
Installed new 7.5.

Now here's where it gets a little bit strange. Upon starting 7.5, its took
an age starting to the point where
it looked like it had locked the machine up, then actually connects (shows
contacts, etc)

Had a look at monitoring the ram it is using, seemed fine, around what it
usually is/was on my system.

However, when initially starting msn, watching the RAM usage for it, it
actually climbs to no lower than 200MB,
yes I typed it correctly, 200MB! (Approx, give or take a few MB or RAM).
And uses almost ALL cpu to actually log in.

It basically keeps hold of this RAM, until msn gets minimized to taskbar,
then brought back onto the desktop again, then gives the ram back to the
system.

Anyone any ideas on this strange/peculier problem?

By the way, its not an infected system, spyware free too
