I have pinned 3 web browsers on my Windows 7 taskbar: Mozilla Firefox 19.0, Pale Moon 15.4.1-x64 and Comodo IceDragon 18.0.3.1. However, I noted a strange behavior with Pale Moon's button on taskbar — When I run Pale Moon, it creates a new button in taskbar, it duplicates it, as seen below.

The normal behavior should be that the application's pinned button just highlights itself when running —just like Firefox's and IceDragon's ones, but not to duplicate itself.
Thanx.
