It's win vista ultimate, WLM 8.1.0178.00
First i'd like to begin how the tabbed chat window looked like before my update:
as you can see the characters, no matter english alphabets or chinese characters are well placed in the middle of the tab. Then it's how it looks after going up to 4.50:
They seemed to be too large, and even i failed to make it more roomy by any means. I just wonder if it's the phenomenon that only happens on me, and how i can get rid of that...
anyway thanks for the kind developers to write us the plugin
