Aspect-Ratio Resizing bug
Not sure if this has been noted but I couldn't find a reference to it.
MaxMSP 5.02
Aspect-Ratio Resizing is useful but if your mouse-drag moves outside the patcher window (i.e., to the right) the object gets a nervous twitch. It seems to cycle through a few different heights even once the mouse is brought back within the bounds of the window.
If this bit of Max is done in Juce then I'd suspect a rounding error in the Component::resized and Component::setBounds or setSize methods.
