I open my palette in the APINotify_Open handler.
But I have found out, that in AC 9, I receive the APIPalMsg_ClosePalette message, later, after it is already left the APINotify_Open handler, but only if I open a file from Start ArchiCAD dialogue. I do not receive this message if I open a file using Open menu. It didnt happen in AC 8.1
Anybody know, is it a bug and why I have to close the palette in case the Start Archicad dialog but have to not close it in case the Open menu.
If it is a bug, how can I find out that Start dialog was used for file opening, so I will not close the palette in this case.
