Just got this whilst building a form.
Can't be exactly sure what I did - I was moving controls around, possibly multiple selections. Labels, buttons & edit boxes on top of a TPage on top of a basicpanel.

[Error] WebUI.wbs (6276,13): Internal error (Invalid pointer operation)

That led me to here when double clicked.

procedure TInterfaceController.FreeElement;
begin
  FElement.Free;
  FElement:=nil;
end;

Sorry I can't be more specific, but just in case it means anything I thought I'd report it.

Tim might be interested in the EWB project itself (to reproduce the
error)  as well so i would suggest zip up a copy just in case.

I assume this only happened once ?  You could be seeing the same hint AV, if it happened while moving the mouse and deleting a control at the same time.

Raul - unfortunately the project doesn't exist any more. It was an experimental one.

Tim - yes, it only happened once, and it could very well have been what you say. Sorry I can't be more precise.

It's no big deal, I just thought I'd mention it in case it was of any interest.
