Is anyone else finding problems with how the site is handling Latex? Firstly I tend not to see be able to see the WYSIWYG version in Preview Post. What I see is I think the first formula I wrote which does not change as I edit it. Only when I actually post do I see what it looks like. Then I when I edit an post the edited version, nothing has changed, or not all my edits appear. I finally get it right just doing the same thing several times, sometimes I may delete some symbols and then put them back. Eventually they have come right for me, but this thing is so cumbersome and annoying I cannot go on using it. I do not see how it could be my computer, keyboard or whatever. Has anyone else had these problems?
