1.I think Undo menu should be disabled when EditField is readonly.

Applied.

Quote:

2.When I repeat right click EditField,the EditField::RightDown method is reentrant.The stack likes the following:
index.php?t=getfile&id=3872&private=0

When I close the parent window,it may crash at the next code line.(It's easy to reproduce it in my project)

In the Upp's help document,"About modal loops and periodic timer events" has talked about this.I think EditField::RightDown should be protected.

Changed to

void EditField::RightDown(Point p, dword keyflags)
{
	keep_selection = true;
	Ptr<EditField> self = this;
	MenuBar::Execute(WhenBar);
	if(self) { // protect from destruction when in menu modal loop
		SetFocus();
		keep_selection = false;
	}
}

I hope it helps (would worth checking for other occurences of MenuBar::Execute as well).
