I have added some icons in the bar tool. When they are not active they look like spot

Hi everybody,

With an add in, I have added some icons in the bar tool (excel). When the icons are not active they look like black spots. I want them to look like the not active traditional windows icons (grey and with the lines of the drawing, clear).

Any suggestion?

Thanks.

Jorge.

If this happens in all systems then this will be the problem with that addin. Try re installing the addin.
