I am developing an application that opens an image in a new window using, at times, windows(). I don't want the user to be able to resize the window (and distort the image). The new window contains a menu item called "resize" that contains three options - "R mode", "Fit to window", and "Fixed size". The default can be set with rescale= (i.e., rescale="fixed" for my use). However, the user can still select one of the other options. Is there a way to either remove the "Resize" menu from this window or remove the "R mode" and "Fit to window" options from this menu item?
Use the following, on a Windows machine, to see what I describe above.
