Very strange behaviour in DemoGrids

[mkromberg]

Run DemoGrids and double-click to edit the first Price (1.23). Change the price to 1.24 and click in the Quantity field. The Price reverts to 1.23 and Quantity changes to 1 (!):

I you now double-click in Quantity, the value appears, but after editing it reverts to 1.

Finally, if you click on "Home", a CellMove is sent but the current cell does not change:

{"NQ":{"Event":"CellMove","ID":"F1.Holdings","Info":[1,1,1],"NoCallback":1}}
