Can you discover if a DRAWMENU is on-screen?

[StephenG1CMZ]

In version 0.1 of my accessibility fingerspelling program, it would be useful if there were a way of discovering whether a DRAWMENU was on-screen or whether that area of the screen could be used for something else.

Also, how do you delete a drawmenu? This leaves a blank Drawmenu on screen.

Code:


EXPORT TRYD()
BEGIN
  LOCAL OKC;
  
  OKC:=DRAWMENU("");
  WAIT;//A BLANK MENU IS SHOWN:HOW TO ERASE?
  MSGBOX(OKC);//IS THERE A WAY OF ASKING IF A MENU IS ONSCREEN?
END;
