Due to a change in the latest Chrome versions (>= 55) menus might have stopped working in your Wisej apps.
Chrome just added new “pointer” events.
Qooxdoo already created all these events before Chrome, so now they are duplicated.
We have logged this issue as WJ-7889 and it is already fixed in our latest development build (1.3.17) which is available for download.
We will include this fix in the new release build and will deploy it early next week.
Best regards
Frank
This was just a temporary issue so I’ll close this question.
