Editing a post actually deletes content

G'day all,

We have a message in a topic that is frequently edited for updates.

"Last edited by [snip] on Thu Jun 26, 2008 12:22 pm; edited 19 times in total"

I am a mod, and update the info in this topic frequently. Usually this works perfectly. The most recent edit has caused the message to "go blank". There is no info at all if I go back and try to edit again - there is nothing in the edit window.

The post is a large table and a small table, about 7cx20r and 7cx10r . Have I hit a char maximum with all the "[td][/td]"'s, or is there another issue occurring?

Thanks,
Chuck68
