Rick,

I found that out shortly after posing the code. This minimizes the side effects:

* FastDoEvents.prg 30-Sep-98

* this workaround speeds up a DoEvent call

local lnRow, lnCol, lcWindow

lcWindow = wontop()
lnRow = mrow( lcWindow )
lnCol = mcol( lcWindow )
if ( lnRow > 0 ) and ( lnCol > 0 )
   * mouse still within VFP window, so it's ok to mouse
   mouse at mrow(), mcol() window (lcWindow)
endif

DoEvents()

>This has some other side effects too... The mouse pointer will jump
>if you're running Top Level forms because MROW() MCOL() won't be
>correct for those forms.
