Dude notification execute on server dont work

As subject says when I try to set some notification and script that has to be executed on server it wont run.
When I change to execute locally, script is started localy on all dude clients, but when I change that same script to be executed on server and push “Test” button it wrote OK in notification window but nothing happens.

I have Dude 4.0 Beta 3.

Does anyone have some idea what can be wrong?

Problem solved… I changed Run mode to “all time” instead of “as a service” and now everything works ok… I dont know is it a bug or not but this is working now…

It will be good that I can use it as service but what can I do…
