AutoCAD 2013 :: Mouse Click Doesn't Stick After Initializing Command

This is happening on all my Autodesk software (AutoCAD, Map 3D, and Civil 3D)(2012 and 2013). . .

I initiate a command (say LINE), I pick my first point to draw the line and nothing happens.  I must click it again to get it ot work.  It only happens when I'm working fast.  For instance:
L (for line)right-click (for ENTER)immdediately try to click the first point of the linenothing happens and I must re-pick the firtst point again

or
 
E (for erase)right-click (for ENTER)immediately try to pick a corner for your boxnothing happens and I must re-create my selection box However, if I go slow it works fine.  For instance, after initating the command simply wait about 2 or 3 seconds and then try to click.  It all works fine there, but waiting becomes annoying now. 

The mouse clicks work fine in all my other software (Excel, MS Word, etc.).  I am having another (maybe totally unrealated issue) with my keyboard.  While typing, my cursor will magically move somewhere else on the screen. I'm using a laptop and have made sure I'm not touching the touch pad.  This may be a completely unrelated issue to the mouse clicks, but I thought I'd inform you just in case the two go hand in had. by the way. . .dynamic mode is disabled, PICKFIRST is set correctly, and I've messed with the 3D Config options.
