Exception rearranging tabbed docking windows

[Kai Iske]

Hi,

we a customer has just caught an unhandled exception when attempting to drag-arrange tabbed docking panels.

Unfortunately the only information I have is the following stack trace:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Hi Kai,

I tried to reproduce the problem, but was unable to. Some information regarding the setup of your application or a similar sample might help me track the problem down.

Gregory,

I will try obtaining further information from the user as to how the docking panels were layed out before the exception was thrown.

If I do find anything, I will open a Direct-Trac incident

Thanks
