Glitch with the JCT

[Barack]

I've been trying to make a car. Sketchup runs normally. However there is a major glitch with the Joint connector tool. The tool just acts like a broken, useless version of the select tool. I am unable to connect any joints when I ctrl+left click, and the ruby console shows this text:
onSelectionCleared
onSelectionAdded
onSelectionBulkChange1
Webdialog set to#Sketchup::Group:0x104d5b20
onSelectionCleared
onSelectionAdded
onSelectionBulkChange1
Webdialog set to#Sketchup::Group:0x103bea00

Sketchyphysics has never behaved like this before. I've been wondering if this is a virus or a malware problem. Maybe someone could shed light on the problem.

p.s here's a pic. Sorry I couldn't capture the cursor.
