[orca-list] Any known issues with simulated mouse clicks in Firefox 4?

[Nolan Darilek <nolan thewordnerd info>]

I have a site which requires me to simulate a left mouse click on some 
links using orca-7--in laptop mode, anyway. This works fine under 
Firefox 3.6, but fails under 4.0.
Due to some of the previously-discussed focus issues, I've had to do a 
few additional things to make this work. Sometimes, for instance, I have 
to find the link text using ctrl-f before simulating the click. This 
doesn't fix the issue under 4.0.
Additionally, I've used the keyboard shortcut that routes the mouse to 
the pointer, but with no luck. I've also tried actually clicking the 
mouse, but again without success.
Since this works under 3.6, it's clearly a regression. I'm wondering if 
it happens to be a known one?
The problem I have with reporting this is that it happens in a site that 
requires login (http://okcupid.com/match). There are a number of search 
criteria on that page that are represented as links, but which can't be 
triggered with enter. And this *does* work on some sites, so it isn't 
universally failing, but it seems to work less reliably in 4.0 than it 
did in 3.6.
If anyone can help me to create a better bug report (assuming this isn't 
a known issue) then I'd be happy to, I just don't know how to do that 
for protected sites, short of expecting developers to create accounts. 
Thanks.
