Due to a faulty wireless mouse (keyboard?), about 30 sessions of Trados Studio 2017 opened up. The error messages were behind the Opening screen and nothing could be done. Of course, it is no fault of Studio 2017. But I would like to suggest that if there is an attempt to open one more session of Studio 2017....it should not be allowed.
This is by design. We could potentially look at disallowing starting many instances in a very short time frame, but this would probably be quite down the priority list as it is a very rare edge case.
