Pages works real slow

Question

Hello, I'm a Computer Science student and I write all my assignments in Pages, I use a lot MathType in my documents to enter equations.
Pages gets really really slow and lagging when typing and moving the cursor after filling about half of the page.
nearly the end of the page it becomes so slow that it i have to wait few seconds for each letter to show up .
when I finish with the current page and move to the next one, it works perfect, again, until about half of the page.
Is there a solution for this?

Answer 1

I met the exactly same problem. I also have to type many math equations in a file. I use mac book pro from 2012, with 16gm ram.
I almost can not edit my old files which contains lots of equations! too slow.
If I create a new file, it works ok only for the first few lines, it getting slower and slower along as the new equations added, which are generated by MathType.
I also turn off the auto check for spelling and grammar, it won't improve. I guess there's problem on the new formate for pictures inserted, since the pages read equations as pictures.
Getting very angry on this damning update!
