[texhax] some postscript specials could not be rendered

[koul]

Hi, I have the problem which resembles the situation described in 
"WinEdt Question or Support Request"
I run MikTeX 2.4  with Yap as dvi viewer and Ghostscript 8.15.
Some latex files with pstricks code included produce error message "some 
PS specials coud not be rendered".

For previous versions of MikTeX 2.1 and Ghostscript 7.04 there were any 
problems.

Thanx for any hints
