For the record, I would strongly recommend you don't install AMD or nVidia's 'control panel' software (Catalyst Control Center for AMD, can't remember what the nVidia equivalent is), or if you do, leave them at their default settings. We had trouble with them in Construct Classic as well - they just seem to be a nice way to break applications. They're intended for games, but they can break anything using hardware acceleration, which both Construct Classic, Construct 2, and all modern browsers also use.
Usually if you do a custom install you have an option to install just the driver, and nothing else. You only need the driver, so try do that if you can.Ashley2012-08-23 19:48:23
