Deleting threads or posts problem.

[centralss]

Well I was selecting certain threads/posts made by a certain user and selecting all, on the right sound of the page. I know there is a 400 delete limit. So I met that, and went to click delete, then it goes to the next page where it gives you the option to soft delete > keep attachments, or the option below to perma delete and the box to enter why your'e deleting.

Well I choose to soft delete, and the entered why, click delete and the screen goes immediately to a internet explorer page not found error!!?!?

Any ideas? I hit the back back and it's still there, hit back again and all the posts/threads are still selected, try again and give me the ie crash!!
