[Yum] Question about GUI yum

[Benjamin Sher]

Dear friends:

[Using Scientific Linux, based on RHEL 4]

Is it OK to have two or more GUI yum programs or do I have to choose one 
and only one GUI yum utility to work with my yum?

By the way, here is my yum version:

[sher at localhost ~]$ rpm -q yum
yum-2.2.1-1.SL
[sher at localhost ~]$


Thank you.

Benjamin
