Howdy, I'm running Mac OS X (ver. 10.6.7) on an Intel MBP (2.4 GHz Core 2 Duo). On two occasions in the last week Safari has reclaiming its status as the default browser without my permission. I'll discover this when I open a link from a third party App and instead of it opening the browser that I manually set to default it will open Safari.*I am running Safari Version 5.0.5 (6533.21.1). I am wondering three things: 1) Is anyone else experiencing this problem? 2) Is there a permanent solution? 3) Is this a potential vulnerability?
