[sc-dev] refresh crashes fix?

[Jan T <sc3@xxxxxxxxxxxxxxxxx>]

Hi
i was playing around with some Pen based guis the last few days and  
apart from a weird behaviour (no error messages printed, but app -  
hang), i'm getting bad crashes, when trying to refresh a non existing  
SCUserView.
Checking for NULL seems to help:

int prSCView_Refresh(struct VMGlobals *g, int numArgsPushed);
int prSCView_Refresh(struct VMGlobals *g, int numArgsPushed)
{
	if (!g->canCallOS) return errCantCallOS;

	SCView *view = (SCView*)(g->sp)[0].uo->slots[0].ui;
	if(!view) 	return errNone;
    view->refresh();
	return errNone;
}

any objection to commit this?

Jan
