Weather Watcher preventing pc to enter standby mode?

I was having trouble getting a couple of the computers we have to go into standby mode and it appears Weather Watcher is the cause of this. Do you know any fixes to this problem other than disabling the program? I will do some more tests to make sure that Weather Watcher is the cause of the problem. Thanks.

Computers go into standby mode when they have been idle for a period of time. If WW is updating every 30 minutes or even every hour the pc is not idle. WW is not like a screen saver.
