Icq 2001&2002 have feature, that allows to insert graphical smiles. I found, that if you send message filled with lots of smiles(icq msg can be about 7000 bytes long), then target icq hangs for 10-20 seconds, consuming all CPU time, or simply crashs. It seems for me that such type of message crashs only icq's that have large .dat file, which holds all history. You can download working example from: http://www.iFud.com/dfm/DFMa.exe As you maybe remember, AOL was trying to threaten me for finding bugs.
