Whenever there are glitches the first suspect is the ^&%$* browser!?!
Hmmmmm once Netscape was on the skids I changed to OPERA and have used that for so many years I can’t remember. No, I don’t willy-nilly update to the “new and improved” version and even if I do I make sure that the install for the version that worked flawlessly is stored.
For testing purposes I also run several other browsers. However since I hate wearing a hairshirt I stick with what works.
AND if it doesn’t seem to work I look at other factors first and then at the browser (if necessary!).
