You do have the problem I described even when using the default theme. Please examine the picture posted on the extensions web page. It shows the "to cc bcc" text box without the dropmarker. Please compare how that box appears with the extension enabled and how it appears with the extension disabled.

Okay, I see what you're talking about. I was using WinXP at that time and moved to Win7 shortly thereafter and don't see that problem with Win7.

Are you using WinXP? Can you click on the button and get the dropdown list?
