Excuse my English :)
I am developing a Mdi-Clx application and when creating the forms I am receiving the message, at some moments : "Invalid Pointer Operation"
The code for creation of the forms is:
if (nameform = nil) then
nameform := Tnameform.Create(Application);
nameform.windowstate := wsnormal;
When closing: (OnClose)
nameform := nil;
Action := caFree;
The Borland of Brazil does not know to answer which is the problem, somebody knows?
