Crash in editor( mFirstResponder Corrupt) 1.5

Been having a fair bit of crashes recently while using the editor. It seems be mostly around drag selecting and alot of copy/pasting.

The crash occurs in the engine at:

bool GuiCanvas::processInputEvent(const InputEvent *event)
{
  // AFX CODE BLOCK (canvas) <<
  mConsumeLastInputEvent = true;
  // AFX CODE BLOCK (canvas) >>

	// First call the general input handler (on the extremely off-chance that it will be handled):
	if ( mFirstResponder )
   {
      if ( mFirstResponder->onInputEvent( *event ) ) <------Crash
        // AFX CODE BLOCK (canvas) <<
        return mConsumeLastInputEvent;  
        /* ORIGINAL CODE
		   return( true );
         */
        // AFX CODE BLOCK (canvas) >>
   }

The mFirstResponder pointer seems have to gotten corrupted because in inspecting it, the mClassName has been assigned to 0xcececece which is a bad ptr. Besides NOT drag selecting and copy/pasting alot ...I'm not sure how to fix this yet.

Anybody run this problem? It's starting to get annoying...I will try debugging it by putting a few asserts to week out where the variable get's set as such..Possibly a memory trashing issue as well?
