I'm sure this is some kind of rank newbie mistake, but I cannot seem to discover what I am doing wrong.

I've got several buttons, each with their "clicked" signal hooked to a slot to do various functions. However, it seems that when the app is running, when the user clicks on one of the buttons, two clicked signals are received by the app.

For instance, one of the buttons uses QDesktopServices:penUrl to invoke the system's web browser and send it to a certain web page. When the button is clicked once, Firefox appears with two tabs, both set to the same web page.

The same thing happens when the keyboard shortcut for the button is typed.

Any ideas of what I am doing wrong?
