[pstricks] Undefined fill style: `transparent'

[Olga Lyashevska]

Dear all,

Since I have updated pstricks I get the following error:


[45]
PSTricks error.  See User's Guide for further information.
                 Type  H <return>  for immediate help.
! Undefined fill style: `transparent'.

l.110 ...,fillstyle=transparent](4.5,4.5)(6.5,6.5)
                                                  
? 

Many thanks,
Olga
