see attached pngs with inconsistent results
You said you wanted to see any problems trying to access the 1P forum in Safari.
So this time I used Safari to access the forum. Then I needed to do a search. See the two pngs which give the results. First I search on "keychain files -dropbox". Notice the minus that the search function dropped. Properly written search functions always allow you to exclude unwanted results - which is what I needed.
The first page said there are 26 results on 2 pages. But when I clicked to go to the next, it then reported there were actually 120 results on 5 pages! This demonstrates a bug somewhere! Note that the Forum software has confused the order of the two pages, so the first page is the second png, and the second page is the first.
I run latest Firefox 3.6.13 and latest Safari 5.0.3 in 64 bit mode on my 2 Ghz Intel Core 2 Duo with 8 gigs memory running latest MacOSX Snow Leopard 10.6.6. and probably the latest 1Password v 3.5.7 updated a few days ago...
Hope this helps convince you that 1P Forum does indeed have problems running in Safari...
