Tell her to stop screaming atcha and do it her D self.
Messing round ... beta testing ? Not the solution to your problem. Surely will lead to more problems. It's called beta for a reason. Your situation in general is odd to me. Trying to figure out where you're going wrong. Cause things aren't adding up. You shouldn't be having problems with one of the many Mint releases. Esp if Mint 9 was working. The lock up would probably be solved by using Mint 10.
Sure things and hardware support have advanced with Mint since then. The issues with 9 you were having. To me sound like driver/hardware or flash/java support ... and/or both.
Yep ... was smart enough to side step the ext4 issue the 1st time I installed Mint 10 on older hardware. Figured older hardware ... newer file system. So I googled and found folks talking about ext4 having issues on older equipment.
Though ... kinda like your wife's style. She sounds like she has her priorities straight ... luvs Mint and hates buntu. Feel exactly the same on both counts. Where buntu is concerned it's horrible junk compared to what Mint makes in the magic minty HQ.
Also when it comes to scumbag megacorps that make me wanna puke. M$ is at least in the top 10 and believe me that's saying something.
