Pmw.Blt in separate windows

[sirotenko at fnal.gov]

Hi,

We have the following question: when we are trying to open two separate
windows with graphs from the
same application, we have the following error:

Linux:onl->python

Traceback (innermost last):

    self.tk.call(
TclError: invalid command name "::blt::graph"
>>>

This is true for both Linux and Windows. Can someone help us to
understand if this is a limitation?
Or there is some trick here?

The error message is similar to one which people receive when
blt is not installed .. but this is not the case here

Thanks,
Vladimir
