HTML Source Editor is changing my HTML

[Robb_Barrett]

I have a table with a complex table built in HTML. The link has several parameter values in it.

I've copied and pasted the HTML directly from Notepad into the HTML editor of my email. When I click "Apply" and then click back to check the HTML, it's changed it.  My & are now &amp. It's replaced my raw HTML for HTML codes.  My spaces appear as %20.

What's going on here? This seems to be a new issue.

I am not sure why this is happening, have you called support?

Can you try pasting the code in and not clicking back in to see the code, TinyMCE editor changes the HTML when you click the Edit HTML tag, so if you Apply and Save, then view the source of the page/email, everything should be as you pasted it. You could be doing the damage by just clicking and checking the code.
