The registration reminder is likely from TealMaster, not the hack. TealMaster is our own enhanced, standard system extensions (hack) manager. A trial version of TealMaster is included with our extensions-format programs as a convenience for those who do not already have TealMaster or a similar manager installed on their handheld. TealMaster can be registered separately for $9.95.
If you have recently upgraded to version 4, make sure you delete the older version of TealGlance (both the calling app and hack) before installing the new version as they use different settings that might interfere with the newly rewritten versions.
