Hello.

I have a problem regarding enable/disable buttons from the XamRibbon.

The buttons from the XamRibbon from my application are bounded to commands. When a command can/can't be executed, the buttons will be enabled/disabled. This works fine. The only problem is that when I load the application the first time, the button's images that are disabled have some black border. 

I have attached a screen shot of this. Do you know if I can do something to change this behaviour?
