I've just unplugged my laptop from my monitor and now whenever a dialogue box comes up, I can't see it. I'm guessing construct hasn't picked up on me unplugging my monitor or something weird like that. since the dialogue boxes would have been appearing where my 2nd monitor was.
Just tried a restart to see if it would fix the problem, it'd didn't :(. Going to re-install construct now and that should do it :).
Edit: This was using the r114 release btw
