The HTML Editor 12.6 was released on Apr 24, 2012 but I just downloaded couple of weeks ago. Using it every day, and experience few times that the content in one of my web pages can be overwritten by another web page.
It goes like this, pageA.htm will have content from pageB.htm. End result is: pageA.htm has the same content as pageB.htm.
I don't know what triggers this but it seems to happen every time I open multiple pages for editing and using the Replace function to replace some texts or a block of sentences.
Does using Win Vista cause all this due to some incompatibility or it merely is the bug making wave inside the HTML Editor program?
Anyone experiencing what I'm experiencing? I hope the CC guys can look into this and remove this bug in the next version.

Just to make it aware to those who are using in case the page has been overwritten and you unwittingly upload to your site. If there's no backup for it, you'll have to reproduce the content from scratch. If it gets on to your website, your visitors will be frustrated to see the exact contents in 2 different pages.
By the way, another issue is with the FTP within the editor itself. Uploading multiple files can cause the FTP to hang half-way thru' the process. It happens when I tried to upload 10 or even more files like that. So, I have to split up into few uploads with 5 or 6 files each time.
I love the cool look of this latest version but the proper functionality is what we need after all.
