I use MT5 on Mac (based on a special broker installation). In general it works without any problems. When I installed the MT5 the window to enter the parameter of the strategy tester was integrated / arranged with all other windows (e.g. chart, navigator etc.). Then I obviously closed it accidentally. When I open it again it will be provided as a small overlay window. When I try to change the size (right down left corner) the content gets completely mixed up (see enclosed screen shot). I also cannot integrate it with the other windows again.
I had the problem already a month ago and reinstalled the MT5. But that can´t be the solution.
Does anyone have a hint?
