Spacing problems

I am experiencing problems with spacing too short after equations. For example, if there is a comma just after an inlined equation, sometimes it's shown just over the equation itself.

I have an example: Finding mod of X^2+1 = 0 to have exacly 4 solutions (look at the answer)

Is anybody having the same problem on this example? Or is it a problem with my navigator or my LaTeX code?

• It might be the same problem as described in these older posts: meta.math.stackexchange.com/questions/6166/…, meta.math.stackexchange.com/questions/6338/… and the other posts linked there. Dec 10 '13 at 16:56
• Bigger than usual, it's exactly what I observed! I thought I had changed the zoom of Firefox by mistake. After reading a bit, it's definitely the same problem. Thank you! There does not seem to be a solution, but at least I don't feel alone. :-) Dec 10 '13 at 16:58
• I recall having seen this effect immediately after posting or editing an answer. Reloading the page got rid of it every time. I'm using Firefox. Dec 10 '13 at 17:02

I don't think the spacing looks too bad here. Are you worried that the $3$ in $13$ and the the comma after it are too close?

For reference to others, the pre-formatted answer is

The smallest solution is $m=130=2 \cdot 5\cdot 13$, with roots
of $x^2+1 \equiv 0 \pmod m$  being $\{47, 57, 73, 83\}$
