Strategy tester can no longer open/execute

[thwli]

Hi 

Suddenly I got an error which I have not seen before. 

The end of the journal goes;   

Core 1- common synchronization competed

Tester- quality of analyzed history is 100%

Tester -cannot open tester chart 

Core 1 - connection closed

It takes quite some time after clicking start, much longer than before.

Then the stratregy tester window freezes, not possible to edit or check anything.
