Very annoying. Any slight move of the mouse causes the window to refresh and start over. How does one fix this?
Using Corona 5, Win 7 Pro.

Ivy maybe?

Well hot damn that was it. Thankfully I have all my Ivy on its own layer, turned the layer off and it works just fine. Will try your method as well. Thanks.
