In trasparent text mode and true color is there an easy way to erase
text? Printing space characters over previous text and then replacing
with the new text seems unreliable. A rapidly changing readout in a
static location, a mouse coordinate display for example, becomes
unreadable because the previous numbers never get erased. I'm not sure
if this is a timing problem or that space characters in transparent mode
dont actually get printed in order to speed up the Allegro code. Any
ideas?

Not if you use the same tabwidth. But the point is, that I was using spaces,
but because of optimal fill it replaced it with tabs.

In Borland C you have to tell the editor if you want this behaviour or that. I
didn't find something in Rhide.
