I was using 1.1 with no problem on a Visor Prism + Minstrel modem, Samsung I300, and Treo 300. AIM 1.1 was working great on my 7135 ever sine I installed it a few weeks ago and today everytime I sign on and it loads my buddy list, I get a fatal exception and I have to do a soft reset. I have not added any new software between now and then either. Very frustrating!
