	I have just compiled PEXtk Version 1.0 based on DEC Contrib PEXlib 5.0
	on one of our Sun SPARC station IPCs. I ftp'd the source code and the 
	library from export.lcs. 


	My question is: "When I execute any of the test programs, shouldn't the
	workstation be clear of any previous images drawn by a previous test 
	program? Whenever I try to execute the test program dtest, which is 
	supposed to read an .obj file and rotate it forever, the image from the
	previous position is never cleared before it is drawn again in a 
	different position. The resullt is a screen full of indistiguishable 
	objects.  clr_test, another test program, appears to be working 
	correctly when double buffering isn't specified.  However, when it is 
	specified, previous images are still displayed in addition to the 
	current one. It seems that the problem lies in the double-buffering. 
	Test programs which do not use double buffering seem to be working 
	fine.


	Could somebody please look into this? Please inform me if I need to
	include any other information in this request. I'm not sure if I
	mentioned all the pertinent details. 

	Thank you.
