MacBook Pro :: Trackpad Seems To Have A Mind Of Its Own?

My MacBook Pro is new (6 weeks old), and I'm an old Mac user.    The trackpad worked fine for the first few weeks but now has it's own ideas on how it should work.   

Sometimes it scrolls, sometimes it just sticks in one place and the only way to scroll the screen is by hitting the up or down arrows.   Can't even raise the scrolly thingy on the right side of the page.    My Preferences are all ticked, for Scrolling and Taps too.   

Often I get a pop up menu when I am just clicking on something.  For ex,  in my yahoo email account,  if I hit a box to tag an email for deletion, instead of the tick mark I get the Open popup menu.   Sometimes I get another menu.   Weird,  no rhyme or reason to which pops up.   OK, I just got the little menu to Insert Link/Insert Image etc.   Two finger scrolling.   Now I am trying to scroll down to submit this note, I get the menu that starts with Cut Copy Paste etc.  Like i said, no rhyme or reason, to what menu pops up - even though I'm just 2 finger scrolling.   Crap, now I cannot scroll down to get to the actions, to submit this.  I'll keep trying.   

Running 10.7.3 

Any ideas or is a trip to the Genius Bar in order?   This is intermittant but increasing in frequency and obviously very annoying.   

I scanned another thread on trackpads, sure seem to be a lot of people with trackpad issues but I didn't find the issues I'm experiencing.

Mac OS X (10.7.3)
