try full screen, and left click the screen before using arrows, I find this usually solves this, the wind is hard to see when it is still but you should see it or at least tell where it is when it interacts with things
good call for clicking the screen first! it's a strange quirk of either full screening or construct - if there was a menu or something first the issue would sort itself out!
Tried again with extra clicks and indeed there is something moving :O Hope I didn't miss it the first time!
Flinging leaves around is fun.
