Scientific Calculator

The right panel of my Scientific Calculator stopped working after years of good service.
It is now a mess of red html text. Click on it opens a purchase offer.
Could anybody help to fix that?

OK, I was first thinking you were talking about a handheld, physical calculator. Then i got to the part about the red HTML text and I thought, is this a surreal situation [SS]. So I had to make the leap to: "Hmmm, perhaps he's talking about the Calculator provided on this site."

So, if you are willing, this can be a teachable moment for you -- especially if you make a habit of communicating this way. Do people often say, "What the heck are you talking about?" when you converse with them? Then the clue to why is contained, here. Think _establishing context_, and _supplying pertinent framework_ -- or if that doesn't make sense, then try putting yourself in other peoples shoes and ask the question,_ would I understand what the heck I'm are talking about_?

So, if I assumed correctly, try dumping the cache on your browser. Especially if you're using FireFox -- there's some sort of bug that causes sites to go haywire and dumping the cache is the workaround.

If my assumption is incorrect, then perhaps you've been hacked

See the attached Screenshot.
In other case reinstall the software.

hmmm interesting How to avoid bugs in webpages How to avoid hacking , !! hmmm Very interesting
Java is a dead duck , also very interesting

However java provides an abstraction btw hardware and software Java is also permission orientated and Java is a completely free langauge which avoids hacks trouble like this and can save you and give you many hours of fun plus me old mucker a nother huge opportunity to go out into the wide world and be paid in excess of £60 000 plus

So here is a java solution for you

Are you on a windows or mac computer? As others have suggested have you tried doing a reinstall of the application. You can always use the full online version. The following link has the downloads and online version.
