The first occurs when using CharCode 13 ( Return / Enter ) in Preview Mode. After the component turns True for the first time, it will continue to output True regardless of the input until you restart the Editor.
The second occurs when switching a SetAppState Component ( in OnLoaded ) to a alternative AppState after having used Preview Mode at least once. From then on Preview Playback does not want to start anymore ( even when switching the SetAppState to it's previous AppState ).
for what regarding the second bug, I might have found something similar.
For what concerns the 'enter' bug, was it present also in the old vers of ZGE or only in the latest one? Because it might be related with the new alt-enter shortcut...
The second bug seems to be a little more severe then the specific localized occasion I pointed out. Preview playback never seems to work anymore unless you manually select the App Component in the Component Tree ( unregardless of having it Locked for Preview ). Seems to be 1.8.0 specific as I rolled back to 1.7.9 to check and did not find any problems there. Hopefully it can be resolved ..
