Clock designer works fine when running under an admin account. However when running on a limited access account it won't save or load *.ekf clock files.
Contact us for a patch/new version of clock designer. Alternatively, navigate to the folder where clock designer is installed.
eg: C:\Program Files
right click on the folder EKITSClockDesigner, choose properties and then click the sharing tab. Check the Share this folder on the network and the allow network users to change my files. That should solve the problem!
