P#D pauses or stalls switch focus in multimonitor in window mode

No , machine specs are  somewhat  different.

old pc =

w7x64 - same

1 295 gtx card and old driver to support it - different 

( i tried this old driver on the new machine but it is just too old and would not run the 500 or 700 series card )

P3d ran on the old machine and the out of focus issue just did not happen.so im perplexed

I was thinking to create a second boot partition on the new machine to see if a new clean o/s partition created the same issue.

Then that would isolate the issue to the o/s or hardware

That seems pretty radical to me and sort of a scorched earth approach but i dont see allot of options at this time

So not sure if ill try  the new partition with w7x64 or w8 x64

Thoughts?
