Just for testing the OnSelection is raised by mouse click ? If the
answer is yes, try to click the cell and keep the mouse button
pressed. If the form appears the grid is still waiting for a MOUSE_UP
(thinking you are holding MOUSE_DOWN to perform a selection) and the
modal form has its own queue, so MOUSE_UP never arrives.
Yes, the modal form appears while the mouse button is held down (for
both GTK2 and Qt).
So, yes, seem that grid expects mouseup
