Weird Track Pad/pointer Issue

Hey guys, had a quick search through the forum but cant find anything about this one.

Its happened a couple of times now and the only way i can solve it is by restarting the computer, Im trying to find out if theres an easier way of solving it or if its a gesture im making on the trackad which is causing it - heres the problem!!! ----

Basically when im using the trackpad, say browing on safai, all of a sudden the pointer on the screen starts sticking to anything it touches, this could be someting on the screen ,a window or a file on the desktop anything it goes over it selects and sticks to the pointer, and i cannnot get it off.
Ive tried turning off double tap to select etc in the options so I know its not that , sometimes if i right click it drops the item but then anything else it passes it selects again.
Its geting very annoying ive lost files and if i go near the dock it drags all my programmes off.

also on my blank desktop space its constantly making a square as if your selecting something.
This problem seems to occur after if either pressed or held down the trackpad and then maybe scrolled, so im wandering if there is a gesture i dont know about that im accidently activating, if so how the hell can i stop this happing its driving me mad, its happened about 3 times this week.

I do a lot of editing and im dreading it happeneing whilst im in the middle of an important edit .

please please can some one help, so far ive found the only way to solve it is to shut down the laptop.

 

no dont do any gaming, dont know if its a hardware issue or a gesture .... Just really worried its going to happen whilst im doing something important and want to know how to prevent it, or at least cancel it if it happens ... Im plesaed its not just me tho, lets hope we find a solution soon!!!

 

no dont even have that bettertouch tool, THis is happening just while Ive been using safari so far, with nothing else open ..... I might try emailing apple ?!???
