Re: [orca-list] Fw: XUL

Hi rich,

I just looked at the test case with latest Orca in FF 3.0 and it's very 
sluggish when arrowing down through the list - it takes several seconds 
inbetween reading each item.  However I tried it on the same computer while 
booted into Windows with JAWS and arrowing down through the list was as 
responsive as ever - no sluggishness at all.
