Thank you for your fast response.
The Problem exists for all Dashboards i have created and includes the switch between the deifferent dashboards.
1. I´m using some Standard layouts and some custom layouts.
2. I´m using display templates, query templates, html files and KPI objects
3. Maschine breakdowns, pareto analysis, maschine status
4. According to this problem, there is no different between using Internet Explorer 11 and Google Chrome 43.
