Problems with keyboard entry of commands

[larryleso]

I've been having an issue with the command line.  When I type commands, like "PL" for example, then hit the spacebar, AutoCAD will start the polyline command and ask me for a starting point.  But it will put an "L" in the command line and I can't do anything until I delete the "L". 

Better explained:

Command:

Type {PL}

Press {spacebar}

Resluting command line looks like this:

Command

PLINE

Specify Start Point:L

It happens with more than just polylines and the L key.  I thought the keyboard was sticking, so I replaced it, and then replaced it with a thrid keyboard and the problem still happened.  I doubt it's a software issue, but I only have the problem with Cad.

Any thoughts?

Thanks

I've been having an issue with the command line.  When I type commands, like "Z" AutoCAD will start the Y command. What is tha problem 

Any thoughts?
