I just started working at a company which uses Skype (the free version) as its main communication platform. The desktop app seems pretty accessible to me so far, but I've noticed a strange issue I'm wondering if anyone knows anything about. Every 20-ish seconds Voiceover will play an alert tone like the one you get when a dialog box pops up. I can never find a dialog box or anything else that would need attention, and since we stay signed in to Skype during the entire workday this is really starting to get to be a pain in the butt. Does anyone know what might be going on?
