If I putch() a new character after restoring ScreenAttrib, it looks ok (so
"ScreenAttrib" should have been updated); but after foo has exited, new
lines on the screen still blink. Moreover, if I type at the DOS prompt:
cls
foo.exe
nothing strange happens, but if I press the enter key many times, reaching
the bottom of the screen, and then I type foo.exe, pressing now enter
gives me the blinking lines. This makes no sense to me.

I'll give it a try, but it's a little tedious to me having to get the
current cursor position every time I need to print a character

Thank you for helping,  Jo.
