How to make tkFileDialog GUI larger?

[John Wheez]

Hi all,

I'm using teh  tkFileDialog to let teh user select a directory. We have 
long names which make
it difficult to view the directories.

For some reason the GUI windows doesn;t expand on Windows like it does 
on OS X or Linux.
Is there a method to make the widths of the  tkFileDialog windows larger 
when using Windows XP?

Thanks for any info.
