I am having the same problem of it loosing focus.  It has been going on for at least a couple of weeks.  The only thing that seems to work is, windows D.  I hate calling tech support with things like this because calling Microsoft I have got on the odd occasion someone who does not know what they are doing and they don’t fix the problem.  They almost create a new one.  I don’t have time to sit on hold, then wait a hour or so while they try and fix the problem.  I have a job which does not entail sitting on hold baby sitting the phone. Then of course there is the problem I ran into this morning with BFO. The dreaded “It should work” then the calls mysteriously being disconnected. I don’t expect that much however, when a product costs hundreds of dollars, I have a right to expect good tech support, not the easy way out of saying for one thing, “It is not a true windows computer it is a mac book converted to a windows computer that is the problem.”  Even a Bonafide windows computer had the same problem.  Time to come up with another excuse.
