on mouse button up issue


I have the following problem:

I have overwritten the function “onmousebuttonup”(i set it up to detect the left mouse button) for a specific image widget,
but when I release the left mouse button over the widget then nothing happens.
Only once I double click on the widget something happens.

I have added an image showing what I have done.

Can anyone tell me why that happens and how to fix it?


I might be wrong but I think some of the input overrides aren’t working anymore. Can’t remember which ones are broken though.
