Okay... so. I didn't have this problem a few weeks ago, but recently I noticed that whenever I opened the Messenger Plus Chatlog Viewer, whether through msn or as a standalone, I've found that the text is enlarged, below are pictures of both examples, one using browser (which is a long drawn out process as compared to using chatviewer) and the other using chatviewer, browser shown first.
Thank, no clue HOW but somehow my IE text size got set to largest... probably while I was messing with maxthon and did that instead of autohide or something. x.x
