Dragging a line between points

[T. R. Ponn]

Hello all,

I've been fiddling with this all afternoon...and I have to be missing 
something obvious.  How do I click on one button (representing a "Pin" 
on a connector) and have a straight line follow the mouse until I click 
on another "pin"?  The visual effect would be to connect 2 points 
together electrically.  After the second click...a small graphic (of the 
first Pin) would appear next to the second pin and the line should 
disappear...it's usefullness ended.  The user would then just continue 
thru all the pins until all connections were made.

This seems simple, and I thought I had done this with HC yrs ago, but 
can't find the stack.

Thanks in adavnce for any light you can shed on this!

Best Regards,

Tim Ponn
