new MSN Messenger Dynamic Background

The new dynamic background that featured in the
lastest version MSN Messenger 7.5 is not a good news
for software engineer like me.

When u are not chatting using Messenger, please dun
let it at top of the screens, (just let it minimized or bottom
of other windows) cause it will use a lot of ur CPU
resource, which then will eventually hang your compiling
process, let's Java.

For the 'clock' dynamic background, it will take 60% of
CPU resource, given firefox running, and YM running,
and system, P4 2.0+ GHz, 512MB.

Is there anyway to cut its 'eating' power of CPU resources?
Hehe...
