iPad: lock window resizing bars not respected after loading plugin

[TriOpticon]

On the iPad i resize the card window to make it larger. I go to Appearance tab and check the Lock window resizing bars? option and save the preferences.  I go back to the Game tab and the window is still the size I set and I cannot change it. So far, so good.

When I load a new plugin, however, the window resets to its smaller, default size. I do not think that should happen.
