Sorry. I think I have to fix this bug in the next version.
I do not want to steal the time of the other engine. It is
just a result of the novelty of my engine and the lack of
my Windows knowledge.

The Problem is I have to decide to fix the version 1.02 or
1.03 which is still under construction. Every 'improvement'
makes the new version a little bit weaker and I plan to
release a 'better' version than 1.02. :-(
