HTML Editor; 12.5 build 406. I use the External Preview often but there is a bug which I cannot work out. This is the 5th or 6th time I've had a document open, visible in the external preview screen. It can be a new document or an opened document with unsaved changes. I get distracted for a minute, maybe I'm online or in email, I'm not sure but when I look back at my document, it's gone. The screen (both preview and editor) are blank. I have only a new, untitled, unsaved blank document - just white space. Last time this happened I was too busy to get on the forum or try to recreate the problem. I'm really furious as I have lost a lot of work in creating this new document and I don't want to spend time trying to solve this mystery but I can't take it any more. Has anyone else experienced this?

Why not get the latest version? It's free.

I would agree. Also, your last order was in 2004. Show us some love here!

I (used to) get email notices to update so I thought I had the latest version. I have it now. Happy to see other fixes which I previously reported. Can't buy anything new. I only use HTML editor, Direct FTP and GIF Animator. Have free life-time upgrades so I don't need the guilt.

You should take a look at the new form builder. No more flash.
