popup windows gone

After updating to yosemite and cubase 8.01.0 Popup windows stopped working. Or well i have 3 tries and then they are gone… If i for example click on import audio, nothing happens… Then i have to restart Cubase, and then i works 3 times and stops again. Thats very frustration for the workflow.

I hope you have a solution.
