I am using docking windows in a child form displayed inside an MDI Tabbed main window. When a panel is unpinned, focus is lost and pinned again, docking control raises some kind of error.
Here are the steps to reproduce the error:
1. Run the attached sample.
2. Unpin the right side docked panel1.
3. Click in "textBox1".
4. Now mouse over panel1.
5. Try pinnig panel1 and move mouse anywhere.
It raises some "Abort retry cancel" dialogs in rapid succession.
Looks like some trace.assert() condition is failing in AHTab class in Syncfusion Docking controls.
Please let me know what is happening.
