The website claims that MRIcron is better - nevertheless, MRIcro on \\gall\Programs\User_Scripts\MRIcro has been updated to the latest version (1.40 build 1).
Enjoy!

MRIcron is better, but MRIcro has a few additional utilities that aren't implemented in MRIcron. I also don't think MRIcron handles data that is 64-bit whereas MRIcro doesn't have any issue with 64-bit data (but maybe this has been fixed since I last played with it).
