Hello Mirek

I did not know that 'virtuality' of destructor is inherited. In fact high level U++ GUI classes like ArrayCtrl have empty virtual destructors.

That was workaround for some old compiler bug.

It is like some destructor supposes that parent control already has not been closed.

Indeed. However, I am unable to reproduce so far.

Is this some sort of new behaviour? (Like: has this started to happen since some time? Have you changed anything in ScatterCtrl?)

Any tips how to reproduce?

BTW, you can copy backtrace to clipboard using Debug/Copy backtrace
