problems with matlab plotgui

I have some problems with Matlab plotgui. I have Matlab 7.6.0 (R2008a) in Windows XP. When I use the graphical interface for PLS-DA, I want to explore the labels, and the table showing the results of my plot from the plot controls, but I have the following message:

PLOTGUI ERROR USING UMTOGGLE AT 9. UMTOGGLE FUNCTION IS OBSOLETE. SET THE CHECKED PROPERTY OF UIMENU INSTEAD. Please can anyone help me with this? I've tried with dstop if error and dbup but i could not solvent this problem.

Thanks in advance
