MS.Internal.WrappedException: Element is already the child of another element.

[Vic]

Hello,

I get the following exception when I use the toolbar and resize, I suppose it happens when builing the overflow list.

This didn't happen in prior versions, I am now using:

Telerik.Windows.Controls: v2009.2.724.1020

Telerik.Windows.Controls.Navigation v2009.2.724.1020

Thanks,

Vic

Note: we needed a Dev build in order to fix the "Dragging windows caused uncontrolled movement" issue fixed in the 7/20 build.  Unfortunately that version is not posted for download. 

Meanwhile, the notes indicate that 7/24 has far more changes which we don't necessarily need.  If this regression only affects 7/24 then we'd be happy to use 7/20 instead.
