SPlus dialog help!

[earworm]

Hi

I have been using splus for a year or so, and all of a sudden the
dialog boxes for statistics have changed layout. Instead of the normal
layout with several pages accessible by tabs, I now have only one page
for each dialog box.
The names of the dialog boxes have now also changed to "menuSomething",
eg. "Linear Regression" has now changed to "menulM".

I have checked all the help menus and the web for a solution, but can't
work out how to change the dialog boxes back to normal.

Can anyone help me? Any help would be much appreciated.
