Ok,
Well, this problem has been eating me alive. I don't want to have to re-install Flash every time I open a browser (didn't matter if it was IE, Safari or FireFox).
I checked out some other bulletin boards and deleting the plug-in from the Internet Plug-in folder was suggested. I tried that a couple times as well as deleting all preferences. No luck.
Then I decided to open up the package of one of the browsers. I copied the the Flash Plug-in there, closed out of it and started Firefox. It worked and I haven't had any problems.
So, whatever browser you want to use, open the package contents and place a copy of the Flash plug-in in that folder. That should fix it.
Thank goodness that one's over.....
