Thanks for the replies, it's food for thought. I will be packaging my code
with py2exe. If there's a snag in packaging them correctly then perhaps it's
best for me to compile the ui. Unless of course someone has an idea as to
what could be Sebastian's problem. Loading the ui file does seem a whole lot
easier however, and having worked with wxpython and xrc, it wasn't much of a
paradigm shift for me I suppose. But hey, we live, we learn. And again,
thank you for the replies, if others still have more, please keep them
coming. They are helpful.
