I type in \boxed{\begin{array}{c}\begin{array}{cccc}16&02&03 &13\\
05&11&10&08\\
09&07&06&12\\
04&14&15&01\end{array}\\ & \text{Figure}\ 1\end{array}} (with the math, /math parts).
Instead of getting the picture of the box with its contents, I just get the LaTex reproduced from above when I do the preview. When I first remove the /math part, do the preview, then insert it back in, presto!, I get the picture of the box with the numbers and figure destination the way it should have happened initially.
Does anyone have a clue as to what's going on?
If you look at what came up with your post, you'll see three ending braces in a row, yet in the MHF preview, you'll see two (and other discrepancies).
Anyways (now I'm talking about my email draft), I have a theory. The LaTex code appears to grow stale (for lack of a better term) so that when I put it into the MHF preview post, it just comes back, but removing and inserting the /math with its brackets appears to refresh and then I get the desired picture.
I'm going to run further tests and I'll let you know what happens.
I'm guessing that the library computer system may have a memory problem which is why removing and then reentering the end portion (h]) of /math (with the braces) seems to reset it (btw there are other examples of computer problems that appear to be memory related from my experience).
