Some symbols incorrectly displayed

[Silvio Capobianco]

Hi All,

I have noticed that PlanetMath seems to display uncorrectly the
inequality symbol, LaTeX command "\neq".

I take as an example this entry of mine:
http://planetmath.org/?op=getobj;from=objects;id=11000
On my browser (Firefox 9.0.1 on Linux Mint Debian edition) the end of
the fifth paragraph is displayed as:
"then f(x1) = f(x'1) with x1 = x'1, so f is not injective."
Of course, the second "equal" should be "not equal". In fact, the
LaTeX source code reads:
"then $f(x_1)=f(x'_1)$ with $x_1\neq x'_1$"

Reloading, with either the browser button or the one in the page, does
not solve the problem.
Rerendering does not solve the problem.

I have only noticed this problem for this symbol: I don't know if
there are more.

Best regards,

Silvio

Thanks silvio; what rendering mode is this?   What happens in other view modes?

Hello Aaron,

Thank you for your message.
The mode was the default jsMath HTML.

After reading your message I tested the other modes.
HTML with images displays OK.
PDF file is rendered correctly.
The "page images" mode seems to me a snapshot of the PDF, and it is OK.

So it seems it is jsMath that has this problem...

Best regards,

Silvio

Actually it looks right for me.

You might want to clear your cache -- I fixed some jsMath mode bugs last night and I suspect this was included in the fixes; but if your cache is still the same it will often stubbornly refuse to reload.

Hello Aaron,

I cleared the cache on Firefox, but the problem did not go away :(
However, I did another test wit Opera 11.61: that one displays
perfectly with jsMath.
So it must be something in my Firefox.

Thank you for everything. Best regards,

Silvio

I've noticed for some reason the caching is remaining more stubborn... I don't quite get it... maybe there is a separate cache in jsMath controls?  You might want to check for that.
