Red dot spontaneously appearing after some time

Some times when I look in the system tray I notice whatpulse has a red dot on the bottom right corner of its icon. At times, it will also have an orange dot on the bottom left corner. When the dots appear, clicks and keys aren’t counted until I restart the program.

So far I haven’t been able to correlate it with any particular action or program.

My OS is windows 8.1 pro 32 bit.
I have no antivirus installed, and UAC is turned off. Whatpulse is set to run as admin.
