I know a number of you are experiencing problems with moving about and enlarging photos in the Gallery section. While I'm still not experiencing this so can really suggest no solution for the moment I did receive the following note from a follower which might help in the meantime:
"I have done some checking about the picture problem at Picasa and it seems that there are a lot of folks experiencing the same problem concerning the big black screen. I used the "help" feature and found that Google is attempting to process things like another photo hosting site and it isn't working to well. Until they get the kinks out someone recommended the slideshow function. I tried that and the pictures come in right away and they are magnified. Plus there is also a full screen button that makes them really large. You will have to adjust the time on the slideshow as it moves quickly."
Hopefully this will get cleared up soon and we can all get back to messing up the floor! Thanks for your patience and thanks Terry, for passing along that information.
