Serious problem with mouse/mouse cursor

I am new to these forums so I have no idea where to post this.

Anyways, here's my problem, every few or so seconds my mouse cursor will have the spiral circle and it will act as if I clicked onto the toolbar at the bottom. For example, if I am typing an assignment, I will have to constantly click on the text box to start typing again. This is a very serious and annoying problem.

Please help me! :(
