Does anyone else have an issue of your forum sig disappearing if you don't refresh the page before editing your post?

When I first post something, the like brackets below it (and below any other posts that have been put up since I last loaded the page) are empty like () and if I hit edit on it while it's like that, I get taken to the advanced editing page. Editing it there and saving it removes my sig from the post.

If I do the initial post and then refresh the page and then hit edit, I get an in page edit box (similar to the reply with quote box) instead of going to the separate advanced page and the sig remains intact.

In the end I have to do this silly little song and dance to do a proper post: post "edit incoming" (or something like that), refresh the page, THEN edit in the post correctly.

It's odd... o.O
