Unity UI problem

UI UGUI
1

There is a problem with UI that is occasionally happening.

ALL UI elements are irresponsive from time to time and i have to manually tick “Force Module Active” in event system for it to work again.

If I restart Unity, the UI works again without doing anything. Once the editor stops playing and plays again, the problem repeats.

Anyone know what the root cause is? I don’t want to check Force Module Active, I don’t want to have to keep restarting Unity.

This hasn’t happened for a while and now it is back, and it is utterly annoying.

I had this issue once but it was back in Unity 4.6

I am using 5.3. It hasn’t happened for a month or two and now it came back again. Can’t find any post regarding the cause only found “not so fix” solutions which was to restart or tick “Force Module Active”.

Both are annoying, and not a long term solution.

Same project, same unity version. Nothing has changed… but this bug comes and go.
