Strange. I do exactly the same and it works ok. The fortran program writes
progress notes into a DOS window, then after completion of execution of the
fortran, the dos window disappears and control passes back into the idl widget
program. Is it possible your fortran program is not ending correctly (eg
pausing rather than exiting?).
I use idl5.2 or 5.3 beta, on win95, spawning to an executable written by a
Lahey F77 or F90 compiler.

When SPAWN returns, call
widget_control, tlb, /SHOW
where tlb is the id of the widget program's top-level base.
As to why focus does not return to where you expect it, I have found focus
in IDLDE pretty quirky. It's never where you want it to be!
