I'm using Windows 386 v 2.1 on a Compaq 386/20 under DOS 3.3 with 5Meg RAM.
I HATE MICE, and so I've installed win to not use one.  I generally 
run WordPerfect 5.0, MathCAD 2.5, and Slide Write Plus 3.0 in 
full-screen exclusive modes, and just use alt-tab to swap between them.

My problem is that when I swap between these applications, the current
app. does not respond to keystrokes if I call it up the first time it
comes around.  Perhaps an example will be clearer.  Say I open WP5.0, MCAD,
and SlideWrite in that order.  Alt-tab,tab,tab,tab cycles through these
apps and the DOS executive.  If I'm in MCAD, and want SlideWrite, I do
alt-tab and Slidewrite pops up.  BUT IT DOESN'T RESPOND to keystrokes!
IF I go through the whole cycle again (alt-tab,tab,tab,tab) SlideWrite
again pops up and everything is fine.  The same problem occurs when I want
MathCad and even occasionally when I toggle to commande.pif (this was not
in the above example).

Any light shed on this problem will be more than I have now.  Thanks.
