getrect Problem - incorrectly enforcing square

getrect help specifies that the rectangle will be forced to be a square if shift is pressed with the mouse click or if the right button is pressed.

However I have some code that involves the user selecting several rectangles in succession and even though I only use the left mouse button without hitting shift, the rectangle is sometimes forced to be a square. There seems no pattern I have spotted to when it will be forced to be a square, but happens around 30%-50% of the time.

Is there some other way of enforcing getrect to use a square that I could be doing by mistake, or could this be a bug? Has anyone else experienced this?

I am using matlab R2011b and image processing toolbox 7.3.

I'm not sure - I don't use that. Didn't even know it existed. I usually use rbbox. You could also use imrect. Try one of those alternatives.
