Steps to reproduce

2) Launch Modo. Ensure Modo is not launched in safe mode.

3) Open the schematics viewport, and add a channel modifier named py.cmScene. 
 
4) Add a comment node to the schematics viewport.
 
5) Connect the comment node to any channel output from the py.cmScene node. 
 
6) Move the cursor over the two nodes and the link between them.
