ZdM version 6.5.2; Agent version mixed 6.5 & 4.0.1.

Application launcher does not consistently refresh and run force-associated
applications at user login. App object is user associated. Behaviour is
inconsistent and random; some launcher instances behaved correctly and
force run immediately following login, some refresh and launch the app
20-50 minutes following login, some never refresh at all. Behaviour does
NOT conform to any one configuration; ie, Agent & Client version can be
anything combination. Timed refresh is configured NO to top of
configuration tree for both users and workstations.

Has anyone encountered this or have any advice?
