In summary, there have been multiple reports of a bug where when editing latex in a post, the changes do not appear correctly in the standard view. This issue has been present since April 13, 2010 and affects all browsers and operating systems. It is suspected that the service provider may have started caching content around that time, causing the problem. Some users suggest that configuring the web server software to instruct proxies to not cache images may help, but it is unclear if this is a viable solution. Additionally, there have been reports of images appearing incorrectly in preview, with some users experiencing images from previous posts instead of the intended ones. It is unknown how this could occur.

When I edit the latex in a post, the changes frequently do not appear correctly in the standard view. Deleting a latex formula when another one follows in the same post also has a strange effect.

Maybe someone could fix the bug in the editor.

There's probably 20 threads about this already, but most of them just say that the workaround is to refresh and resend after each preview. It appears that we've had this problem since April 13, 2010. According to our LaTeX guy, chroot, nothing changed on the server around that time. The problem is essentially the same in all versions of all browsers, on all operating systems. This strongly suggests that the service provider started doing some weird caching around then. Has anyone been in contact with them? Maybe Greg just needs to ask them to configure an exception.

I don't know this web stuff well enough to know if something can be done on the server. Is it possible to configure the web server software to instruct proxies to not cache images?

It seems to me that something else must be wrong, in addition to the fact that somebody is caching something. How does a transparent proxy know what image to use from the cache? Isn't the image identified by a file name or something? When I previewed these four LaTeX images, I got the two images from my previous post instead of 1 and 2, but 3 and 4 were fine.

[tex]1[/tex]

[tex]2[/tex]

[tex]3[/tex]

[tex]4[/tex]

Can someone explain how that's possible?
