Empty overlay after startup makes working impossible
When starting Bizagi Modeller 18.104.22.168 (on a Win7 64bit machine) the GUI appears, a blank project is loaded but then a kind of "overlay" appears. It has the bizagi logo on it and a close icon on the upper right corner but it can't be closed.
The bizagi application itself (main window) does not react. Only possible way of exiting is the Windows task manager.
Can anybody help me here?
