Occasionally something happens such that when I press the minus key the 'window tool' opens. It's been so long that I can't recall what it's called, but it is the Windows tool for maximizing/minimizing/restoring a child window. The keystroke to call it up is alt-minus (similar to the alt-spacebar command for invoking the tool for a parent window).
It will happen when I'm drawing a line by station & offset and try to enter a negative offset; Windows sees the minus sign and takes over, opening up the child window control thingy. Another way is if I try to start the Layer command on the command line by preceding it with a minus sign; -LA.

Yep, that's been bugging me also.
Especially in the instance when you are a poly line that runs through consecutivly numbered points.
I discovered a fix that seems to be permanent at least during the C3D session.
When pressing the minus key opens up the Windows Keyboard Shortcut to resize the window:
1. Click with the cursor in the C3D command line.
2. Before pressing any other key, press 'esc' one time.
3. Control should now return to the C3D command line, and further presses of the minus key shouldn't bring up the Window Resize shortcut command.
I have this problem as well when drawing feature lines, which often have negative grades. It's very irritating, hope they've fixed in in 2012.

I am currently having this problem. I'm currently between Civil 3D 2011 and 2014, soon to be 100% on 2014. I have this problem in 2011 and I recently noticed the behavior in 2014.
Most of the time I must press escape 3 times in order to get out of whatever causes the control tool to open.
Sometimes all I need to do is press minus, then the next key twice, whether it's a command or a number (the first time is ignored, second will go to command line)
Turning off the Menu Bar has never helped
Turning off the Ribbon has never helped
Toggling LOCKUI to 0 and then back to original value will often stop it. Sometimes it's necessary to keep LOCKUI at 0. Sometimes it doesn't matter.
Disabling contextual tab states will sometimes help
(Options > Selection > Ribbon Options > Contextual Tabl States... > Contextual Tab Display > Do Not Switch to Contextual Tab on Selection)
