1. Cuny's Text GUI minor cosmetic bug
When using a 50 line screen, after running a program from inside the EE
editor, the message asking for a key to continue, does appear at the 24 (or
25) line, and should be at the bottom of screen. (Not new, neither
annoying, but I've thought I should report it...).
Jesus. (Again, twice today!).

Thanks, I just saw that the other day. It'll go on my 'to do' list. Most of
the time, I stay out of alternate screen resolutions, so I tend not to see
bugs associated with that. The fix is trivial (just check the screen
resolution, and use that value). I should be posting a number of fixes some
time after New Year's.

3. Re: Cuny's Text GUI minor cosmetic bug
I just took a look at my code, and it already checks for screen resolution.
Apparently, Euphoria is unable to detect the screen resolution unless it
has been set by the current program. I ran into a similar problem with
trying to save screen shots when the screen was left in graphics mode.
Apparently, Euphoria does not actually ask the VGA what the current
graphics state is - it just checks an internal flag. So if the Euphoria
program that you've shelled to changes the screen resolution, the calling
Euphoria program is unable to detect the change, and thus incorrectly
reports the current screen mode.
Is this correct, Robert? Or am I being dense here?
The only "fix" I can think of under these circumstances is to put the
"Press a Key" message at the top of the screen...

That's true. It's due to something in WATCOM's graphics
library. I can't easily fix it. That's why system() has a second
argument that allows you to restore your original graphics mode
after running a program that might change the mode.
To avoid problems, system("xxx", 0) or system("xxx", 1)
should be used whenever xxx might possibly change the
graphics mode. If you are sure that xxx will not change the
mode then use system("xxx", 2).

5. Re: Cuny's Text GUI minor cosmetic bug
I've found something on this:
I run Euphoria under Win/NT 4.0.
If I configure the DOS box as 80x50 (both scroll buffer and window)
permanently, and I also configure EE to 50 lines, everything is okay.
If I only configure the DOS box is when the problem arise.
I've got another problem with EE. (I use it bound as EE.EXE, with bind, not
bindw, and EE.EXE is in %EUDIR%\BIN).
I was trying the nice ModeX demo from Pete Eberlain (that will hopefully
solve my Screen Saver problem, thanks to everybody...).
I edit Demo.ex to change parameters, (i.e. # of balls). If I try to run or
bind it from inside EE, I get an error:
"Attempt to subscribe an atom"
on one early line:
"constant spheres = virtual_screen(length(bmp[2][1]), length(bmp[2]))"
that is okay, since the program runs well outside EE...

Whoops. My fault here. I am very lazy when it comes to error checking.
The problem is a few lines earlier when I try to read in the bitmap
"spheres.bmp". I made no check to see if bmp is actually loaded, in the
case that it isn't bmp is an atom, not a sequence. "spheres.bmp" needs
to be in the same directory that "demo.*" is executed in. Sorry about
this.
