It's version 2.3.0 non-commerical for Windows. My OS is Windows 2000
Professional SP4. Using this same version of Qt for a Ruby-based
implementation of a similar app I didn't experience the access
violation crashes when invoking the setCentralWidget() method. It's
sporadic, as the crashes sometimes take 2-3 widget opens/closes to
happen. Other times it takes more. Trying to debug the crashes the
script never makes it past this method. Here's an excerpt from the Dr.
Watson error log:
