[PyQt] problems with PyQt book custom view examples [Win7]

Everything else seems to be working apart from the little bug with saving
application settings to Windows registry. It does "remember" the application
size and position, but recently used files do not get loaded when the
program is relaunched. I checked, that recently used program data gets
written to the registry (at least some kind of byte array) on application
termination, but somewhere in the application loading process it gets lost
or is not recognised.
