Came home from 2 weeks vacation last night and found that a new version of iStat Pro was available. I downloaded and installed the application, and it seemed to work properly. This morning I turned on my iMac and the iStat widget just shows up as a small black rectangle in the dashboard. The small question mark and the small "i" are there, but clicking on them does nothing. So, I downloaded AGAIN and reinstalled. Same results. The black rectangle just sits there on dashboard and will do nothing. Any suggestions would be appreciated. NO . . . WAIT. Just launched dashboard again, and it is working. Strange ? ? ? ? NOW I have the same problem with the "Radar in Motion" weather widget. What is going on?
