slow invision ?!

[Shurikn]

Hi all

I really like this script but one thing is making me going insane.
This script is soooo slow when running in background.

For example:
When i'm playing a game and switch back to irc, it takes like 15 sec. until the screen has finished loading... and another 15 sec. until my text gets send into the channel.

Any ideas how to fix this problem?
