Steps to reproduce the bug: Hover mouse over something that has a long tooltip (like the "changed" LSL event word in the script editor).
Observed results: The tooltip doesn't wrap (with a 1024 screen width anyway) and stops after "...CHANGED REGION,".
I believe this also happens with a long "Message of the Day" but I don't remember for certain (and the current one isn't that long--and changing SL's window size doesn't have the same effect on the "Message of the Day" window as a lower screen resolution--which I don't feel like dorking with now--would).
Expected results: The tooltip should wrap if too long for the screen width.
