Yes, those are exactly the problems I am asking about you are right.

OK, for the invisible buttons i will be doing the “trick” of the .xml or the “fill area” to make them visible again for the moment.

But with the appaerance of the buttons, would like to get rid of the border,that’s all. I am trying to set the blendmode as you suggest but I cannot do it in a client startup script. Found a thread that talked about this but still i am unable to do so.

```auto
from com.inductiveautomation.ignition.client import IgnitionLookAndFeel
from de.javasoft.plaf.synthetica.util.Synthetica2DUtils import BlendMode 

IgnitionLookAndFeel.setBlendMode(button, BlendMode.ALPHA)

```

Thanks.
