I have a tab control object on my Access form and have changed the style to none so that the tabs are not visible, however when I click on where the tabs would be it still changes the pages like as if they were there.
Is this normal behaviour and is there any way to prevent the tabs from being able to be clicked?
This is by design. You could take advantage of this setting to display images where the tabs would otherwise be so that it appears to the user that they are clicking on the image to change tabs.
As you've already figured out, you should set the Visible property to False if you want the tab to be both hidden and disabled.
