Hi Christophe

That's good, it sounds like you are on the right track now, at least.
If FileBox eXtender is capable of affecting the height of a standard dialog
in weird ways when it's turned on, it's certainly capable of the rest of the
behaviour you are seeing here.

I'm pretty sure utilities like FileBox eXtender usually hook windows API and
do other low level trickery to achieve their effect. Just like is often said
about virus checkers on this list, turning these things off is often not
sufficient to disable them. This is likely to be becuse the hooking or
filtering or service creation is an expensive operation, so they find it
easier for a "turn off" to leave it enabled but return immediately when the
functionality is called.

Try to temporarily uninstall then reboot, and see whether your entire
problem goes away.

This doesn't mean that the Stefan will be able to fix it, or that there is
anything to fix in TSVN at all. But at least you will have a reproduction
recipe.
