Attach a project demonstrating the problem
https://www.dropbox.com/s/gu0kposemtju4zl/flash.capx?dl=0
The steps to follow to reproduce the problem in the project
Press "Run layout" button.
What you expected to happen
The sprite object should not become invisible if the "Flash" behavior lasts 0 seconds.
I think the behavior code should check if the "duration" argument it receives is greater than 0 before acting.
What you observed happening instead
The sprite object becomes invisible when a duration of 0 seconds is used in the "Flash" behavior.
