I have wm scheduled application scheduled to run daily, start 0:15 end
23:59 repeat the action every 21 minutes.
Everything work, but after some time (from several hours to several
days) wm stop to call my application. If I open wmscedule window and
press "refresh" my application immediately run and for some time run
every 21 minutes as expected.
W2ksp4 client 4.9sp2, zfd6.5.

Any sugestions?
