I have very little information about this problem, but have had several people report it.
In some instances, the font size on interface controls does not scale properly? and this leads to text getting cut off.
I attempted a few things to cause this problem on my own computer, mostly changing the resolution, but I couldn't seem to reproduce the issue.
The problem has been around for quite a while, so its nothing caused by the most recent update or anything like that.
Maybe it has something to do with Windows themes or other settings...
EDITS: OK, I've reproduced the issue on my own computer. Not sure if this is the case for everyone, but it can be caused by changing Windows 7's font size. Not sure if theres anything you can do about that...
