Tab Control "Hover Fore Color" doesn't work properly when called from Navigation control

[John M Gray]

Has anyone else seen this problem?




I have a form called "Preferences", with a tab control with four tabs, as shown in the attached figure. I have the active tab font set to black and the non-active tab fonts set to gray, and the hover fore color set to black. When I open the form in Form View and hover over a non-active tab the font changes properly from gray to black, and if I click on the tab to make it active then the color changes to black and the other tabs are gray. So the form is working correctly.

I have a main form called "MainDashboard" that has a navigation control as shown in the figure below. One of the control buttons is set to open the Preferences form. This works fine, except that when I hover over one of the non-active tabs I see a flash but the color never changes from gray to black. If I click on a tab then the color changes to black. Something about the main form or navigation control is preventing the hover fore color from working properly.

I did a search on the Internet and the only thing I found was a description of a button hover fore color not working with a navigation control if the Back Style is set to transparent instead of solid. I tried changing the tab control on the preferences form to solid, but it doesn't work. I still get a flash but the color remains gray. I went through every form and control setting, and Access options, to see if there was anything else I could find that might interfere but I haven't found anything.

Hmmm, I placed the form with the tab control within another form, that is within the main form navigation control, and now the hover is working fine. Why does this feel like I've entered the Twilight Zone?
