Triggers behavioral issue

Hi, 

I have created 4 rectangle shapes and 4 layers as popup text. I’d set the trigger for each rectangle shapes to show its respective layer. The popup has a close button which on clicking, hides the layer.

All these triggers work perfectly most of the time, however, its unresponsive to any of the shapes or the close button on the popup. It takes loads of time to trigger or when you move off the window and come back, it automatically refreshes to the right state.

I am not sure what makes it behave this way nor could find a solution.

Any help on this is much appreciated.

Thanks in advance, Cheers!
