I had this same problem (Mandrake9.1, Python2.3.3/Tk8.4.5 as well as
Python2.2.3/Tk8.3.3) that I got error mesages on askstring() dialogs:

TclError: grab failed: window not viewable


Because it happens with both python/Tk versions I don't think it's a
build problem.
Maybe it's a Tk-bug?
It drove me nuts for a while until I wrote my own dialog widget.
Any hints here would be very appreciated.
