Table border keeps breaking

Would Simon or somebody mind taking a look at this please?

I've put a coloured border around a table here. (The Irish phrases)  But when I look at the published version, the green frame keeps breaking.  I'll refresh the page and it's fine again.

Is that my computer or Wizzley?

Jo I am looking at it in Firefox and it looks OK to me.

I'm in Firefox too. Is it still ok if you refresh the page?

Mine seems to alternate. It was broken when I published. I freshed the page and it was fine. Then I answered your comment and it was broken again.

It's like there's a kink in the border, about 3px wide, halfway down.

Thanks for checking for me.

Edit:  Screenshot:

Looks fine here, FF

Looks good. (Chrome)

I'm strongly suspecting it's my computer now.

I'll see if the graphics driver needs up-dating.

Thank you everyone for checking. In reality, it's not my computer it needs to look ok on, it's those belonging to my readers.  If you're all satisfied that it's not breaking, then I am too. <3

Jo try a "clean up" and clear your cache - I find if things go "wonky" that often helps.

Oh dear, Simon, it sounds like the border went wonkier for you than it did for me.

I'm not going to worry about it. The majority of people are reporting here that it's fine for them, so I'm assuming it's also fine for the readers. It's only happening intermittently for me too.

Thank you for looking into it; and that goes for everyone else who checked too. <3

(AJ - Just ran CCleaner. First check and the table border looks fine! Good call.)
