Sorry, Scott, I misunderstood your original message.  I read it over
again, and I now understand your question.  I think your use of the word
"window" there threw me off <grin>.

The alt-enter toggle only works in Windows.  I don't remember it working
in any of the DOS shells I tried (long, long ago...).

What you are seeing is the way the laptop hardware and video drivers
handle normal text mode (as opposed to graphics, such as used by
Windows) on the display.  I have an IBM ThinkPad 755CD at home that uses
most of the screen for the text mode display, and it runs TRLog
beautifully.  I have also used several older Compaq laptops that do just
what you are describing, and boy, it's annoying.  I owned one of them,
and that was one of the two reasons that I sold it to get the ThinkPad. 
The two newer Compaq laptops (7400 and M700) which I now use at work use
all of the screen in 25-line by 80-character text mode, so they would do
just fine with it.

Unfortunately, I am not aware of any way of changing the size.  I think
it's a hardware-related function, and therefore there may not actually
BE any way to change the size, if my understanding of how the display
hardware works is correct. 
I'm posting this reply to the list in the hope that someone with more
exact knowledge can fill you in and either confirm or refute my
assertion, and if the latter, provide you the answer you desire.

By the way, the second reason I ditched the Compaq for the ThinkPad was
that I dislike the mushy "feel" of the Compaq keyboards as intensely as
I like the crisp ThinkPad "feel".  And no, I don't work for IBM or sell
