GroupBox bottomline

Hello,

Is there a bug in Xojo 2018r1.1 in the display of a groupbox.
When a groupbox is displayed and the caption property is not empty the bottom line of the groupbox is not visible.
When the caption property is empty the bottomline becomes visible.

Is this a known problem ?

What operating system? Do you have an example project that replicates the issue?

OS is Windows 10 Pro.
I tried a little project with two groupboxes and there the lines are visible with or without caption.
I do not understand why my project is not displaying the bottom lines only when caption is set.
PS this is not for all the groupboxes in my project.

??? will further investigate what goes wrong.

Thanks
Regards
Etienne
