Bill,
It sounds as if the AOL software has set itself as default while the program is still installed, the only thing I can suggest is check the options within the software itself and see you can dis-associate the file types you want to open with PSP, or uninstall AOL altogether if you dont use it. I for one stay away from anything AOL for purely reasons such as this. If the AOL program starts itself when you boot your PC, type "msconfig" in the run command and untick the AOL program icon located in the "startup" tab.....reboot your PC and try my first suggestion again!.
