Grid is Crashing Tablet PC

I have a RadGridView in my application that is crashing the application on a select few tablet pc running Windows XP tablet editiion. Because our (state) department is going the tablet way, I really need to get this fixed. Not just disable tablet input services on the pc.
I'm thinking the problem is because the grid that is causing the problem is heavily customized with Data Templates.

The crash happens when they attempt to scroll horizontally on an editable grid. It's been reported that if InsertRows and DeleteRows is disabled, then the grid behaves normally. So far this error has only been reported by users running on a tablet pc.

Also, another user reported that when he tried to activate the TabItem where this grid lives, the application crashed only when there were items bound to the grid. If the bound collection had no items, it didn't crash. His problem was resolved by disabling Tablet Input Services on his Windows 7 tablet pc.

Could someone look at my code and see if I've done something I shouldn't.

Reflect changed position of tiles back into the ItemsSource collection

Hello,

I have a WPF application in which I load a multipage tiff file and use the TileView Control to display the BitmapFrames in tiles. The end user needs to change the order of the pages(tiles) and the save the tiff. The dragging of the tiles works ok but I also need to change the order of the objects in the ObservableCollection<PageViewModel> which is bound to the ItemsSource of the TileView. How can I achieve that ?

Thanks,

Alex.
