Auto update turned off solved the issue.
It would be perfect, if a workaround could be found for this, at least for the dials created for Webmails!
Anyway, thanks a lot for your support.
Thanks for the prompt reply! Will try...
BTW, one year ago, this was not an issue despite auto update is on.
Something is happened after the updates...
