With five builds of Windows (XP, Vixta, 7, 8, & 8.1) and two bit rates, as well as more than five different browsers for Windows that are commonly used (IE, Chrome, Firefox, Opera, Safari, SeaMonkey, MaxThon, WaterFox to name a few), requiring three different plug-ins, a simple "auto fix" to encompass all the possibilities available, would be about five times the size of the plug-in installer. When you figure in that people are using IE8, 9, 10, & 11, Firefox versions between 4 and 28, Chrome between 21 and 33, and Opera versions from 6 to 21, it gets even more complicated.
Sometimes it's like when you need to change a tire.
You have to pull over off the road.
Shut the car off.
Open the trunk.
Take out the jack.
Take out the spare.
Jack up the car.
Remove the hubcap if you have one.
Remove the lugnuts.
Remove the tire.
Place the new tire on.
Hold it in place whil you put the lugnuts on.
Tighten the lugnuts snugly.
Lower the jack and torque the lugnuts.
Lower the jack completely.
Put the hubcap back on if you have one.
Put the flat tire in the trunk.
Put the jack away.
Close the trunk.
Get back in the car.
That's a lot of steps but they're necessary to do it right. It'd be great if cars had a "flat fixer" that simpy repaired and refilled the tire while you drive, but that wouldn't help if you have a blowout and there's nothing to repair. You'd still have to replace it yourself.
What you described in your first thread was the Flash equivalent of a blowout. The whole thing needed to be removed and replaced. Can you continue driving on the rim after a blowout? Sure, but it's better to replace the tire when it happens. Same with Flash. You can keep using it while it crashes all day every day, but it's better not to.
