hey forum people.... i have a mac (21.5 inch, 2.5 Ghz Intel Core i5) running OS X 10.9.4. For the last maybe 6 months, I've had an issue where if I view a flash video in a browser (mostly I do this in Safari, sometimes do it in Chrome), the computer will get stuck in the buffering. This doesn't happen consistently, and when it does occur, it's after watching video for a while (more than a couple minutes). I won't be able to connect to anything on the internet. If I turn wi-fi off, then turn it back on again, it fixes everything. Anyone have any ideas on why this happens?
