I've nearly managed to get everything working now under 0.4.6 so that i can release this into a pure 2.0 runtime environment. I've been searching for old DateField bugs but have been unable to find an answer so i'm appealing to the older hacks to see if they remember if they were able to get it working in the dd-mm-yy format ??

this appears not to make much difference..

<ext:DateField ID="extStart" runat="server" Format="dd-MM-yyyy" ></ext:DateField>
