For years I've relied on my children to fix computer problems (although, since I made the switch to Apple, such problems are far rarer). But now it's time to grow up, in tech terms, and try to solve my own problems.

Luckily, I've had help: Google. Whenever I encounter a glitch or can't figure out how to complete some task, I Google the problem. I almost always find a solution.

Last week it was documents that I was unable to drag from my desktop to the trash; they just kept bobbing in place, refusing to move, as this message was displayed on the screen: "The item can't be moved to Trash because it can't be deleted."

What now? I Googled the phrase, and the search produced a link to a Mac forum that had a simple solution - no call to my son required.
