Unable to pulse.

Version: 1.7.1
Username: Allegiance
Windows: 7 x86 (32bit)
Admin: Yes, WhatPulse also has admin privs.
Errors: None that I can see.

According to WhatPulse logs, the program is pulsing but does not give a confirmation (in the form of the tooltip popup) like normal that it is doing so. Am I doing something wrong?

Maybe teh Preferences?..
