problem after update world 1.5

[kingofland]

Hello, since the last update of DCS World 1.5, in the mission editor , when I click on the icon to open a file , the icon turns blue but nothing works . I can not open my mission file.

If I created a new mission everything is OK, I record everything is OK, but if I want to open it again; the icon turns blue and no job.

With DCS World 1.2, the file open icon turns blue too, but the work is OK and I can play the mission.

thanks for your help
