Hi,
On NT/2000/XP, you will not be able to use the serial port,
once it is assigned to a mouse.
On 95/98/Me, you can do this, but you will lose the mouse
for the remainder of your Windows session.
Mouse output is not very useful for tests anyway.

Very simple; just wire the string to a scan from string function and

Now the date/time to seconds function takes a cluster of these numbers

Two things you could try.

create a constant and set it to Minimized.

Actually, the colors for icons are quite limited, the max. is 256

exact, I do the 16 color icon (middle) first, then convert
