I use both Poco and PocoPE. When I toggle the Strip HTML / Sanitize / Imagedownloading buttons in PocoMail, they switch for all open windows (preview and individual messages). This is not good.
PocoMailPE does this correctly. That is, a toggle only affects the window that is being toggled and not all windows.
I hope this is corrected in version 4.
