Hi Wingy99, this page is a bit eclectic. Can you point out more specifically the ones that need attention?

I'm not seeing any broken borders.

I notice some errors in the CSS rules like lines that are supposedly (?) commented out that start with a "/" (comments should be enclosed in /* */)

• Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K)

         TD.t1 {
t            spacing: 0 0 0 0;
            padding: .6em .5em .4em .5em;
            background: black;
            border: ridge 10pt blue;
         }

         TABLE.t2 {
            background: brown ;
            border: ridge 3pt darkred;
/            padding: .2em;

         }

There are also errors with the border-style (probably border should have been used).

         a#hv2:hover {
            background: green;
            color: yellow;
            border-color: blue;
            border-style: 10px ridge;
         }

Hi jscher2000 and cor-el... very nice of you to reply... thanks! And thanks for trying to verify the seen problem. Maybe I have a problem locally with a graphics card or something.

Here's a screengrab of what I see...

As one control-mousewheels (scales) the page, graphics "debris" sparkles in those gaps... what one could call pixel noise, I suppose. Some of that pixel noise can be seen in the corners of the F and G elements. The noise animates and changes (sparkles) during the control-mousewheeling.

I guess I better start looking for a local cause. Again, it was very nice of you two to respond and be concerned... thanks again. Cor-el... thanks for the cleanup look-see on my css, too. My incompetence (or lack of paying attention to specs) shines bright, eh?  :)

I'm not seeing any such artifacts.

Try to disable hardware acceleration in Firefox.

Hi Cor-el... that fixed me right up. You're a genius! Well done. Sorry if I was a hassle for you or anyone else.

Fixed me up too
