Penny has a lot of info that she shares and has done webinars on a number of different topics. I remember one on the use of the FabriCalc and another on EQ7.
I have a VERY good, up to date computer, been running Windows 7 Ultimate for 6 months before it was available to the public, and Google Chrome as my browser. (4GB of RAM so that's not my problem.)
All that said, I had no problem logging in, but after many attempts to watch the various webinars I had to give up. Other webinars run fine, so I contacted Penny (she is a sweetheart) and she too could not figure out why I can't see any of her webinars.
