RHEL5's ImageMagick /usr/bin/animate behaviour has been changed from RHEL4.7 to cycle between images

Issue

Our customers would like to restore the behaviour of /usr/bin/animate to be similar to the one in RHEL4.7.
In RHEL4.7: /usr/bin/animate to open two gif images. Images cycle between the two gif images using SPACEBAR to compare both images.

$ animate screen1.gif screen2.gif

In RHEL5.3:  Command above will cycle / rotate the gif files  automatically and it terminates afterward.

The users would like 'animate' to behave like it was in RHEL4.7 where by the the two gif images would not auto cycle by itself and the user is able to cycle between images using SPACEBAR.
