ImageJ 64-bit runs within an admin account, but only the 32-bit version will run if logged in as a user. So far, changing permissions on the 64-bit ImageJ for non-admin user accounts has not resolved the problem.
I've tried on 3 different Intel Macs with OS10.6.2, some with Java 1.6.0_17. Has anyone else encountered this, or solved it?
