I had a similar issue. No "aw snap" but just blank pages, no webpages loading at all (blue browser screen). IE working fine. If I shut down OA, Chrome worked fine. All of a sudden, after using Chrome for months.
I put the path to Google Chrome executable (C:\Program Files\Google\Chrome\Application) in OA's Exclusions (Under Configuration, Options, Exclusion tab). Everything was then fine. But later I was uncomfortable with that, in case something bad should implant itself in that folder. That might hobble OA's purpose.
So I got rid of the exclusion, put OA into Learning Mode, launched Chrome. Everything still fine. Took it out of Learning Mode. Still fine. Rebooted, launched Chrome, still fine. I'm using Chrome to post this right now. Everything now seems good again.
