Hi Timo, Thank you very much for replying with an instant solution!
Suggestion for future release: a setting in the configuration to enable/disable the automatic instance_update_now action and/or set the timeout by the user. In the meanwhile I can use the recompiled version with this code change. Problem solved for me.
