This is happening because of the 2 new lines of code inserted in the MouseMove method of Control.Prg in version 7.10. The error is occuring at line 629, because ::bMMoved is NIL :-
- Code: Select all Expand view
628: else
629: Eval( ::bMMoved, nRow, nCol, nKeyFlags, .T. )
630: endif
I do not know the purpose of introducing the two new lines but if we change "else" in line 628 to "elseif VALTYPE(::bMMoved) == 'B'", all code using drag and drop is working fine. I do not know if my proposed change will create any other side effects but for the time being I am able to make my present software work with the above small change.
I would be grateful if Mr. Antonio can look into this and advise.
