I'm writing a text-editing program in BC++ to take advantage of the 
extended text modes of my video card.  The windowing structures work 
fine in the normal text modes (80x25, 80x43/50), but when I switch to 
the 132 column x 44 row mode, I get sixteen (16) mouse cursors! 
I move the mouse, and sixteen text cursors float all over the screen, 
leaving "garbage" characters behind them.

I want to make my application self configuring, so that it would adapt 
itself to the text resolution of the system when the program was 
called.  (So that I (or any one else) could set the resolution to the 
desired width and height at the dos command line and call my program.)

Do I need a special video driver to run in extended text mode?  (I 
noticed that the conio.h functions would not show up in the extended 
text mode in some other programs.)  My video card is built into my 
motherboard.  It has a Western Digital chip and 512k video memory.


Looking forward to any response.
