Dear Matix,
Thank you for contacting National Instruments.
To address your question, this commonly occurs when the decoration isn't added to the tab, but is only placed above it. It is easiest to do this by placing the object beside the tab control, select it, then using the keyboard arrow keys, manuever it where you need it onscreen. It should have little shadows projecting below it showing that it is floating above the tab. When run, the shadows disappear and the object will appear to be a part of every tab. You could actively hide it for the exceptions.
If you do not want the decoration to appear on every tab, make sure upon creation of the decoration to include it inside the tab control. There will be no shadows around the decoration.
Let m
e know if you have any further questions or if this does not resolve your issue.
Thanks again and have a great day!
