I use the tab control in quite a few of my applications - I am currently running 2017 R2
I normally set the background of each tab to a different colour and set the tab part the same colour.
PLease see the attached picture I am sure I am setting it correctly - selecting the tab page and then the tab backcolor - but it doesn't change
I am doing somthing wrong - Is this a bug - intentional etc ?
thanks in advance as allways
