Two finger click and then drag not working on my macbook pro 2009

I'm not too sure how to explain this, but when I click the track pad down with two fingers and try to drag with two fingers still pressed down the mouse wont move. I need to be able to do this as in some certain programs I use this is needed. What do you think could be wrong with it?

Thanks,
Ryan

Try:

Click and hold with one finger

Then place 2nd finger on the trackpad

use the 2nd finger to move the item while the 1st finger remains in place

It's kinda hit and miss with that. It works about 40% of the time, the rest of the time the mouse doesn't move at all.

A 2 finger click is going to bring up the context menu - it's not going to drag anything.

It used to work for a while and then for a short amount of time before it stop working all together the cursor would shake when right click dragging. Not sure what went wrong with it
