I can't launch probes in ME2

[kamariehe]

Hi, I have a small very annoying of not being able to launch probes.

I'm using a laptop and have no mouse. The left and right touchpad buttons work for everything else, but for whatever reason the left button doesn't work when I'm scanning planets. Is there any way to change the key to launch probes? Or do I have to get a mouse?
