NTabControl maxes out CPU on hover

I've been using the NTabControl extensively in my application. I noticed today that my application updating hung unexpectedly. Watching the task manager I saw the CPU for my application max out the system.

This can be easily reproduced by launching the "Examples C# for Nevron UI" application that came with my license. I'm on build 11.12.14.12.

1) In the "All Examples" list select the "Tab Control" example.
2) Check the "Has Close" and "Show Close Button on Each Tab" checkboxes
3) Show the Windows Task Manager so you can watch the CPU spike
4) Hover the mouse over a non-top tab making the close button on the right show
5) See the CPU spike and stay maxed out

It seems as though it locks the UI trying to show the "Close" tool tip and never does. I tried in my application setting the ShowToolTips property to false but this didn't do anything.

1) If I set HasClose and ShowCloseButtonOnEachTab to false I can still get this to occur but its much more difficult to find the mouse hover spot where it happens.

2) Is there something I can do in my license to fix this issue?
