Hi all,
when I use CURSOR in a while loop to keep track of where the mouse has
been, if I move the mouse fast enough, I end up missing a bunch of
pixels that I know I visited. When I plot it it looks like a dotted
line rather than a continuous line.
Is there a way to be sure to capture *every* single coordinate that
the mouse visits? in direct graphics if possible?
Many thanks,
Gianguido

Oh, no, it's possible. The only caveat is that the programmer is also part of the software
delivery *and* he/she must be willing to submit to endless "now make it do this" requests
and code rewrites from the user.
:o)
I don't really know what an "anti-hatered" shield is.
cheers,
