Well that certainly explains it.

OK, I see now. That option will be quite useful then.

This has been happening since day one for me with the translator. It isn't a big
deal, just press "Alt-Enter" to restore windowed mode. I agree that it's a little
annoying, but it certainly isn't a critical flaw worth deleting a perfectly good
compiler with nearly hundreds of bug fixes,
new features, improvements, and optimizations since the 10.x series.
Remember we're talking about DOS here, I hardly ever read any DOS related
discussions on the EUforum, which makes me suspect that few people are using it
anymore. In fact, I doubt that many people would care if you one day decided to
drop support for it (however Igor and I might get upset).
I dont know of a way to bypass this, but perhaps you might find something in the
Watcom C manual: ttp://www.openwatcom.org/ftp/manuals/c_readme.pdf
If not, maybe you can request it for a later release of Open Watcom if it is
really all that important to you.
