Hi ROOTers, 

I have encountered possible bug in ROOT PS generation. 

I do these commands:

	gROOT->SetStyle("Plain");
	TCanvas* c2 = new TCanvas("c2","c2",800,600);
	TPave* pave = new TPave(0.1,0.1,0.9,0.9);
	pave->SetFillColor(0);
	pave->SetFillStyle(3013); // supposed to be cross-hatched
	c2->cd();
	pave->Draw();
	pave->SaveAs("test.ps")

	I see cross-hatched pave in the canvas

first:
	if I try to look at the resulting file test.ps using ghostview
	like this:
		ghostview test.ps
	I get nothing, cursor turns into wristwatch and nothing happens
	
second:
	I looked at ghostview options and tried '-noantialias' (what the
	heck)
		ghostview -noantialias test.ps
	
	does display a picture. But the pave shown is not cross-hatched
 	it is as white as snow,		

	I am using some 3.02/07h Fermilab made root version build 
	for Linux under KAI. 

Can you reporoduce these problems and if yes could you fix them?

thanks,
Dmitry Litvintsev
