The Floor Plan Editor example shows some behavior I am currently also observing in my own application. When dropping an item from a palette, the canvas shifts down and the menu bar disappears. How can I remove this?
In my own application, the problem is worse: I have created a panel on the left side of the window. When I drag something from the palette to the canvas on the right side, everything shifts left and the palette completely disappears. However, this happens only in Internet Explorer, but not in Chrome, Safari or Firefox, there the behavior is as expected.
Is this a bug or am I missing a setting?
