Richard, how did you make this post?* I have seen a Mac that was unable to upload a pic.* The "button" to upload wouldn't "click".* Could be the version of Java?
I made the post using Internet Explorer, which I prefer not to use.* I avoid MS's IE and Outlook because I prefer to minimize my exposure to hackers.
The upload buttons, the preview button, and the post button all do nothing under*Netscape.* I'd be surprised if it's a Java version thing - I keep my SW very up-to-date.
