I'm working on a program that requires user input to enter (when
queried) strings and so forth while at the same time running in mode
13h with Allegro's keyboard installed. So far, Allegro's GUI using
d_edit_proc suits the bill nicely. However, I've noticed that I don't
seem to be able to use textout reliably anymore- sometimes (and
seeming randomly) textout decides to ignore my FG and BG colors,
making them the same (both FG, I think) so textout text isn't
readable. SOmetimes it corrects itself. But it always eventually does
it again when I am using GUI routines too. When I don't use any GUI
routines, I don't see this problem. Lastly, the GUI graphics/text
always look fine. Anybody else ever see this set of circumstances?

My reason for wanting textout instead of just the GUI d_text_proc is
that I want to paint text on the screen that I'll erase myself later
when I'm ready to blit a new screen up- sort of like a "Wait while
processing..." message. That allows me to gauge roughly how long each
procedure is running (and know everything is working right). I don't
know exactly how to made a GUI routine that would require this little
extra code or attention, and given that I have 20 to 30 functions that
all need to do this same thing, I like it that simple.

If someone can tell me how to fix my textout problem, that would be
best for me. Otherwise, another GUI approach with a "fire and forget"
sort of way like I have

Alternately, if there is a different way to get user variable input
when in a graphics mode with Allegro's keyboard handler, I'd like to
know. Although I will say that d_edit_proc, in conjunction with atoi()
and atof(), etc., does a superb job, it would suffice if it weren't
for the textout problems.

Please post response here. Thanks
