User clicked on invisible tab page

[Judah]

Just got a bug report in our software, where it appears the user clicked a KryptonTab page with .Visible = false. Somehow, the tab showed up in the UI and the user clicked it, resulting in an exception:

ArgumentNullException

Message = Cannot select a page that is not visible
Parameter name: value

User Comments: was on a note, and the "History" tab in preview tabbed info was visible (no idea why)...so, i clicked on it...

Do you a sample project or set of steps to reproduce the issue? Thanks.

[Judah]

Phil - no, afraid not. This is an error report from software running on other users' machine; I've no idea how to reproduce it, only passing the error information on.

Here is a repro for the bug

Just tried your test application on my internal code and it worked fine. Showing the group again the invisible page was indeed invisible. I believe this has been fixed in the latest version.
