[chimera-dev] Using Pmw widgets

[Mateusz Dobrychłop]

Hello,

I apologize for the delayed response. Using Toplevel() instead of Tk()
generates the same problem. Actually, the problem is that my code used to
work perfectly before the system's reinstallation and after the first launch
of Chimera.

I somehow managed to make it work - but I have no idea why the line of code
makes it work and, still, why it wasn't necessary before, but it is now:

x=Pmw.EntryField()

When this is typed before any other usage of Pmw toolkit, the whole rest
just works. I really wonder why this is a solution, if you have any ideas
what is happening, please let me know ;)

Best,

Mateusz
