Good catch. You're right that there may be more bugs of that kind.

The problem is that I can't initialize the methods before running 
node.lua because I don't know what kind of node it is yet.

The only simple solution I can imagine is returning (0, 0) or something 
from pipmak.mouseloc() as long as thisCNode->complete == 0. Or perhaps 
undefining pipmak.mouseloc altogether in that context would be even 
better. Otherwise we'd have to redesign the whole node loading process. 
Do you have a better idea?

Is there a real-life reason why you want to query the mouse location in 
node.lua, or are you just trying to break things? Could what you're 
doing be moved to onenternode?
