[BUG] - Java Script Error on RMB Click (Uncaught Exception)

[WalterEckalnd]

Using the mouse to right click any button (e.g. "Select Profile", "Website") results in an "Uncaught Exception" Java script error.

Steps to reproduce the behavior:

1. Open R2Modman v.3.2.11
2. Right click on any button (like the one labeled "Website" that is supposed to take you to a mod's webpage)
3. See error

Expected behavior
Right clicking these buttons should result in nothing happening at all.
