Was not! It's all relative, you know?
You could try and treat the subject with a little more gravity.
How do you know I've not? You don't. At least not until you open the box.
The cat was dead. They scanned the box with an MRI scanner.

MRIs don't work on that. They lack the prerequisite string attachment.

Sounds like a knotty problem to me...

MRIs do get tied up years ahead, but they can be got hold of. They use them on Mummies, so I can't see why they can't use them on a pussy box.

Just spotted something. I accidentally used ALT-0190 to render the ¼ symbol, but that is properly ALT-0188. Instead, ALT-0190 renders the ¾ symbol. So everywhere you see a ¾, it should actually read ¼. Trouble is, the text box in which I was typing this fed the results back to me in such a small font, that I couldn't see the mistake. Sadly, advancing years are taking a toll on my ability to read small text.

However, I've discovered a nice feature built into the latest version of Google Chrome. If your mouse has a scroll wheel, holding down CTRL whilst operating the scroll wheel changes the zoom magnification of the page, a feature I'll be using often in future. :)

Once you've used the CTRL-scroll feature to make things more visible, you can simply re-scroll back to normal magnification after posting. :)

Yeh, I've found that feature fairly often, by accident. But I don't view the internet much, with the keyboard on my lap. I like a wireless keyboard, even when using my laptop.

It would be nice to have an extra button on the mouse, that you could assign to the ''control'' function of the keyboard. Or a button in chrome, that you can click to engage the zoom function. Or a slider for zoom, like in word.
It is a very nice feature, but not available enough.

You don't need a mouse for that. Keyboard combination CTRL+ enlarges and CTRL- shrinks.
