I have just upgraded to EWB3 and have an issue converting a EWB2 app.  In formA I execute formB.showmodal. FormB contains a Tgrid that is bound to an EDB dataset When I close formB formA then executes the formB.Onclose event that frees FormB and sets it to nil However I then get the error 'List Index 1 out of bounds'  I can get round this by setting the TGrid dataset propery to nil before closing formB This appears to be a bug  Please confirm  

Thanks in advance
