Re: [orca-list] Mouseover support in Orca has arrived!

[Jacob Schmude <j schmude gmail com>]

Hi
I've played with this a bit and so far it's handled all the  
mouseover's I regularly deal with. One interesting thing I do notice  
though is that, in the case of some mouseover popups, using the focus  
mouseover object command is not strictly necessary, i.e. routing the  
pointer to the object is sufficient and the mouseover object appears  
directly where you are at in the page. Not all mouseovers act like  
this however, in which case the focus command is very useful.
It might be preliminary but so far I'm having a lot more luck with  
this than with any support for mouseovers I've seen anywhere else.  
Keep up the good work, I for one appreciate all the effort that is put  
into Orca.

   The major difference between a thing that might go wrong and a  
thing that cannot possibly go wrong is that when a thing that cannot  
possibly go wrong goes wrong it usually turns out to be impossible to  
get at or repair.
