FNC Ribon performance

I'm using the TMSFNCRibon for a cross-platform software.
Under Windows, when you collaps the ribon, it is very slow. I have measure the performances with GetTickCount :
Windows : 750
Mac OS : 250
Ubuntu (in a VM !) : 63
And on a very hiDpi screen (more than 200%), the windows is shaking all around the screen.

and the property Collapsed is not well managed :
when you set it to true (ribon collapsed) et when you click on a tab, the ribon uncollapse but the property collapsed is still True.

We'll investigate this here as soon as possible. Thank you for the test-project sent via email.
