Duo 270C

[Liliana]

Have a Duo 270C with a dock (haven't yet tried the dock) and its been 
sitting there for a while since the trackball is very sticky, the cursor 
doesn't move much at all unless I move it lightning fast, still it 
doens't work most of the times, what can I do to fix the trackball?  I 
tried getting the ball out but it's so hard.  I used to have a 230 that 
the trackball would come appart  easy, how can I get it out without 
damaging it?  I can't get it out no matter what like someone put glue in 
the plastic  to keep the ball in place? (I wonder)

thanks
