IC5141 question ？

after I installed IC5141 on redhat5 , I print "icfb "but the terminal told memany errors:
" X Error: BadWindow (invalid window parameter)"
how to fix it ?

search for the legit license here. or disable your xorg to see which one it is....

Install your IC5141 in your RHEL3 or RHEL4, but not RHEL5 because not supported.
