1. Get an autocomplete popup to show. 2. Click the back button on your Intellimouse. Expected Results: Popup disappears and navigate to previous page. Actual Results: Popup remains and navigate to previous page.

Well, I don't have an Intellimouse, but isn't this basically the same problem as bug 257354? I have done some suggestions in that bug, but I'm unsure what is the right approach to solve this. (I'm not a c coder, you know. I just could help with the other bugs, because they were fairly easy.(I appreciate you're cc-ing me, though.))

I think the problem with this one is we don't have a listener for NS_APPCOMMAND events. As such, the autocomplete popup doesn't receive an event for these extended button presses.

I think the checkin for bug 257354 should have fixed this.

This is working now. (20041007)
