Hello! I am currently running Mac OS X 10.4 Tiger, and have ample disk space available. However, I am unable to run ooVoo without the application freezing, thus forcing me to close it. This often happens without me even clicking anything, and usually occurs just before or after I attempt to sign in. The application crashes consistently, and before I am able to call anyone. Any suggestions on why this may be occuring would be greatly appreciated, thank you (:
