External Window Kills Canvas Refresh
 

When you grab a external window generated by Graal, the canvas stops updating - this is a old problem but I was hoping that it could finally be addressed.

Regardless, I'm curious why it does this to begin with... does it generate the window with the same thread which it also generates the canvas?

External windows still use some old delphi code I think that's why there are some bugs. Stefan just needs to convert it all to the C++ stuff.
