??? Attempt to execute SCRIPT graphicsversion as a function - but all plot files are default

I am trying with anything - for troubleshooting sake I made two x and y vectors with 3 values and asked it to plot - this is the response.

>> plot(x,y)

??? Attempt to execute SCRIPT graphicsversion as a function:
/Applications/MATLAB_R2009b.app/toolbox/matlab/graphics/graphicsversion.m

Googling suggests a mismatched name somewhere between the function and the script.

Steps I have already taken:

• I'd previously got an issue which said the toolbox path cache was wrong, so updated this using the option in general preferences
• removed all folders from the file path except default
• moved the graph2d path to the top/bottom to see if I can force it to be called first
• identified there is only one file called graphics version.m (/Applications/MATLAB_R2009b.app/toolbox/matlab/graphics/graphicsversion.m)
• identified all files called plot:

      which -all plot

This is why I'm stuck - I can't see anythign here except that which is installed by default... does anybody have any suggestions?

Considering a full re installation at this point >_>

UPDATE

I think this is a java issue. (Matlab using 1.6 but mac only has 1.7) No idea how to fix it but this question is no longer relevant - I'll resubmit with the right question!
