I updated to the latest firmware 5.1, and after a dozen page loads, no need to load the page twice. There was a comment about 5.1 that I read somewhere that the issue with Safari crashing has been fixed. Mine used to crash with 5.0.1.
Anyway, this just came out and is looking good. Now if it will fix the auto-speller running perfectly good words together, i can turn that back on.
