While working on my game today, I ran across an issue while testing. It seems that keyboard shortcuts for the browser that I'm using (such as ctrl+x or ctrl+s) still get called while running a Construct application. This occurred for me in Chrome, Firefox and IE. So for example, pressing ctrl+s will attempt to save the web page instead of just performing an in-game action.
I found a couple of postings in the manual and on these forums indicating to me that these shortcuts are supposed to be intercepted:
Maybe this is better off in the Bugs forum, or is there some sort of known workaround?
