Wondering if anyone has a solution to using Timbuktu Pro 4 and System 7.5.5. If running the computer hangs on shutdown; I can see the Timbuktu icon disappear in the right upper corner after selection of shutdown; then can use mouse only and computer hangs and doesn't shut down -- need to unplug or reset. If I remove Timbuktu from start up then it shuts down fine. Thanks for any suggestions. Is there a better version of Timbuktu to use than Pro 4? Seems to be a software issue.
