I don't trust either
a few people i know with either / or , have had their accounts hacked, and their names taken, this i heard is largely due to ICQ now keeping your lists on their servers. I will stick with 2000b

and even 2000b on certain games will mess with the pic, and u can sort of see a message come up, in single mode or double. Just minimize ICQ to the tray, does it for me.
