## LaTeX preview problem

I've been having severe problems trying to get LaTeX expressions to look right using preview -- it seems that only the initial processing run sticks, any corrections made don't seem to register, at least until I post the thread (everything looked fine then). The issue is persistent across Firefox and Internet Explorer, however, both at least seem to get one independent run each -- so I can write something in FF, preview and correct, then copy and paste to IE, check again; however, any subsequent changes don't seem to stick. I have even logged out, closed FF, and logged in fresh, to no avail. Looking around, I saw the problem discussed here, but no solution was offered.

Basically, the problem is, if I write something, containing an equation, then preview it, see a mistake in the equation, correct it, and try to preview it again, instead of seeing the corrected version of the equation, the old one will continue to be displayed; and even weirder still, when I go and enter a new equation before the original first one, it seems as if the output is just 'moved up' one place: where the new first equation should display, the old equation one turns up, etc.

Of course, I can always post uncorrected and edit, or check every equation with the LaTeX preview, but both solutions seem somewhat tedious -- of course, if I have to live with it, it won't kill me. But is there some better way of dealing with this? Is anybody else experiencing similar troubles?

 If you just do the preview, and then hit the reload button your browser, you should see the recent changes. This has been a workable solution for me.

I was under the impression I'd tried that, but maybe I did something wrong -- let's see:

$$e^{i\pi} + 1 = 0$$

Well hot damn, it works! Don't know what I messed up previously... Thanks for the help, phyzguy!
