Hi Of course, there's nothing stopping you using Qt3 and Qt4 apps side by side. There is no issue with shared library versions since Trolltech used completely different names for the Qt4 libs. It will waste a bit of RAM having both sets of libs in memory, and you might need to juggle your PATH if you switch between the two versions a lot. A+ Paul
