Hi there.
I was using the Q1 2007 release until now, but am attempting an upgrade to the latest (2010) version. After redoing the references the program compiled without any big problems. But now, when the software runs, and I drag any tab(document) into another docking position it complains:

System.InvalidOperationException was unhandled
Message="Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on."
Source="System.Windows.Forms"
StackTrace:
at System.Windows.Forms.Control.get_Handle()
at System.Windows.Forms.Control.get_InternalHandle()
at System.Windows.Forms.Control.DestroyHandle()

at System.ComponentModel.Component.Dispose()
at Nevron.UI.WinForm.Controls.NUIDocument.PerformDispose()
at Nevron.UI.NDisposableObject.Dispose(Boolean disposing)
at Nevron.UI.NDisposableObject.Finalize()
InnerException:

The tabs are created like this (ctlWatchList is a user control with a datagrid):
ctlWatchList m_ctlWatchList = new ctlWatchList(this) { Dock = DockStyle.Fill };
NUIDocument docWatchList = new NUIDocument(WatchListTitle, -1, m_ctlWatchList);
m_DockManager.DocumentManager.AddDocument(docWatchList);


Do you have any ideas about what the problem could be?
What other information will you need from me?

I'd really appreciate the help.

Kind regards,
Martin
