I'm using some no longer supported software (very recently) from http://www.multidmedia.com/software/xenon/
that uses the Chromium Embedded Framework (CEF) at it's core, to allow desktop Apps to be made from HTML.
I've even found the source code (pre compiled)
(just search 'You pressed the space bar!')
It's only an issue on OSX compiled Apps (.app) but not an issue on the PC end (.exe) files.
Thanks in advance!
