1Password locks up IE9 on Win7 64 with version 188.8.131.527. When I press auto-fill, and select the password to fill in, the whole of IE locks up and "dings" if I click anywhere on it. The only wat to fix it is to go to task manager and kill the iExplore process.
This problem is so common for me now, that I have stopped using 1Password really - as I have lost completed things on other Tabs. I am a heavy user of tabs - and have read the other threads that talk about this problem being tab related, and list the problem as fixed in an earlier Beta - but it clearly isn't.
This happens on both my laptop and desktop. I followed the instructions about "factory resetting" IE, which was inconvenient - and it has had no effect at all.
1Password is effectively useless for me now, as I daren't press the key for auto-fill.
