Hi Koldo,

I recompiled my spearfishing app yesterday and tried it a bit and ... fell on a total application/desktop freeze.

I am working under linux and after a code compare and a few tests I found the modified line that was causing the trouble:

void Scatter::SetDrawing(Draw& w, const int& scale) const
.
.
if(antialiasing)		//  && w.IsGui())	IsGui() is always false in Linux
false in Linux
	{
		ImageDraw imdraw(3*l,3*h);	
		Plot (imdraw,3,3*l,3*h);
		w.DrawImage(0,0,l,h,imdraw);
	} else 
		Plot(w,scale,l,h);
.
.

I just re established the following test condition or turn off antialiasing

&& w.IsGui()

==> if((antialiasing)  && w.IsGui())	//IsGui() is always

And it worked again.

The 'Scatter::SetDrawing()' is called from the following method

Drawing Scatter::GetDrawing() const
{
	DrawingDraw ddw(6*GetSize());
	SetDrawing (ddw, 6);
	return ddw;
}

Any ideas ??
