I keep getting a lot of errors with this WYSIWYG system.

Formatting looks odd. Text sizes are changing when I am entering, going back, and all of a sudden text is bigger/smaller. Or something disappears.

Now I added a code here http://timeless.vforums.co.uk/action/modify_post/board/staff/topic/11/post/11/page/1

a ... appeared and when I go to edit it the WYSIWYG vanishes.

I have done work with many different WYSIWYG editors and lets face it, none of them are perfect. Especially not when they're trying to combine both high levels of functionality with high security. However I use the WYSIWYG editor here on a daily basis and very rarely have any issues with it, at least not ones which cannot be resolved by some common sense. I recon I have more problems with Microsoft Outlook than with this editor.

You have seen the guide I'm writing on WYSIWYG hints and tips. Have a read of it. It covers things like removing the formatting from text you have copied (which it sounds like your main issue is). I've also written an edit to the "UBBC" pop-up box which enables you to edit and post the UBBC version directly without it being parsed through the editor which should provide a good work around for those who want to edit the UBBC or post a lot of code tags (this is not yet live).

I tried bringing up the UBBC box, and it came up blank. :[.

Gonna take a look at that guide XD
