Signing off is not the same as crashing. One is it simply exiting, the other would have you sharing some error message.
Since AOL is its own support world, all I can offer is that you try GAIM from http://gaim.sourceforge.net/
If you want to pursue this issue, clarify your post.

I'm getting really pissed off now! On both of my computers, AIM signs off and on at least 10 times in one hour. I am using version 5.9.3690. Please, any ideas?
