Mac Messenger

OS v9.1
Internet Explorer v5.0
Mac Messenger v3.3 and below (I haven't tested this with
v3.4 yet)

IE has a feature that pops a small balloon that contains
information about links and such. This feature is akin to
the Balloons Help feature in the Os. Wherenever one of
these balloons comes up (for more than a second or two)
it wll freeze the computer. If one presses command
option esc the finder can be forced quit (the finder
always has to be forced to quite in these situations) and
you continue to use the computer sans finder.

This bug ONLY occurs when MacMessenger is opened
otherwise these balloons while not crash the computer.
