running several instances of Singular at the same time

Hi all,
can several instances of singular run concurrently without any problems? For example to calculate Groebner Basis for two different ideals.
I am using version 4.0.2 for windows.

Yes, several instances of Singular may run at the same time.
Pay attention to routines in Singular which call external programs
(like "4ti2.lib" etc): the created filesnames for the rtransfer of the data
may not be unique - but all of this does not ocur while computing Groiebner bases.

Thank You!
