Tabcontrol and "allow multiple colors" option is greyed out

[GeirHHH]

Hi 
I am moving an old labview program (2011) to a new PC, but experienced that the color in Tabcontrol is "white" while it was more grey looking in the old PC.
If i try to change it, the option "allow multiple colors" is greyed out and not selectable for the existing tabcontrol in teh old labview program.

How can i to set the option "allow multiple colors" to be selectable again?
I manged with adding new tabcontrol and change the same option, but not the existing tabcontrol in the old program where it is greyed out.

Most probably that old VI uses a tab container from the "System" controls palette: those System controls use the color scheme of the OS - and so you cannot change certain properties (like colors) on your own. (This would also explain the change in appearance from "grey looking" into "white"…)

The "System" tab does not allow "multiple colors". To change its color you need to change the color scheme in the Windows system settings.

Btw. it would have helped when you had attached the VI with that tab container…

Thanks, that help a lot. 
I converted("replaced") the system tab container to an ordinary tab container, and can change color now
