What type of internet connection are you using? I get something similar on my satilight connection when there is an issue at the down link location. for me reloading the page makes it work better, I also wait a few min and it clears up.
can you use apple mail or Thunderbird to download messages?
After clicking on "gmail" the bar starts, but stops about 2mm from end.To open the gmail I have to click on "Load basic html" wait for it to change , click standard gmail again and it opens straight away..a bit frustrating.
Does anybody have this problem? Any idea how to make it open straightaway?
