Maybe people have trouble when their onboard memory is close to maxed out. I only have 4 gb and my puter bogs down sometimes. If the system doesn't have enough memory to start a program to play a file does it opt to save it instead? I don't know.
I got 8gb. 3.5 gb are free. It's as though I opted for "Save This Setting," but I didn't. And I can't find out how to reverse that decision.
I changed my Firefox settings for these file types from Always Save to Always Ask, and got things back the way they were (meaning I now have my Play/Save dialog box back.) I have no idea how those got changed...Firefox updates are supposed to keep your settings. Perhaps these settings are not part of my FF Profile.
