Help! Half of my table has disappeared in Design view!!

Hi,

I've got a fairly large table going in Dreamweaver 8. Its inside a CSS
box and has smaller tables inside some of the lines. Its for an alumni
list with little bios for people.

It was working fine for a while but when I opened Dreamweaver yesterday
I couldn't see a lot of the bottom of the table in Design mode. The
code is still there in Code view and it shows up if I preview the page
in my browser. I don't know what the problem is. I've tried restarting
and looked for anything wierd in the code.

Another odd thing is that several rows will show up for a while and
then disappear again. It never gets below a certain point though.

I definitely don't want to finish this project in code. Any ideas?
