PMW Notebook does not work.

[vasu]

Hi:

I recently downloaded the PMW version 0.8.3.  While running the tests,
all the mega widgets workfine except for Notbooks.  While tryingout the
notebooks, an attribute error for "raise".

I am running it in RedHat 5.0 Linux.
Python version is 1.5.2.
I version of Tcl/Tk is  8.0

Can anyboy say what i am missing?

Thanks
