I've downloaded (or should I say "checked out") the SVN version<STRIKE>, but while compiling IrrTest I've got some Access Violations somewhere in CreateDevice function, so I think I'll wait for working HelloWorld example</STRIKE>.
Sorry, false alarm. It seems that someone forgot to update IrrTest Delphi project with new source code . Everything works neatly on Lazarus.
And it seems that to make it work on Delphi copy-paste approach is not enough - window doesn't paint in blue color, it is just "see-through". I wonder, what difference between Delphi and Free Pascal (Lazarus) makes this happen?
