Hi there, I've been mucking around in an attempt to fix one thing and in the process I've altered Thunderbird so that it has lost the ability to present any of its windows in GUI format - no icons and all appears to be text format. I also seem to have lost the ability to display HTML format email properly and have no idea if HTML format for new messages or replies, actually works. It all started because, after I installed Firefox and then duckduckgo over the top, the colours and lines of the web search page seemed washed out. Previously black lines became a light grey, with the search box in the middle of the web browser page almost invisible. To find it, I have to click somewhere in the approximate location so that the cursor provides the location on the screen. Other areas of the search screen as well as any graphics on the page were also washed out. The URL list resulting from the search was also a bit washed out, but the web pages that opened were normal including all pictures and text - obviously because that content lives somewhere else and away from my computer :-). Trying to "fix" the washed out colour issues, I managed to make some unwanted and mysterious changes to TB settings (how/where I have no idea) to the extent that TB's ability to display in GUI format no longer exists. The "options" window itself is no longer in GUI format, and all the rest of the screens presented in TB are the same as the Options screen - non GUI. In addition, my ability to change colors by using the "tools\options" window is very restricted. Please see screen captures of "tools\options" page and a screen capture of the New Email screen. So far I've re-installed Thunderbird - over the top of the previous installation - something I didn't really expect to make any difference (gee it felt good to be right for once). I simply cannot work out why this has happened and have spent quite some time to resolve - I cannot find any references on the web. I'd like to avoid having to do a full uninstall of TB, particularly because I'm not confident that it would work - so I'm seeking your help please. I'm hoping its just a settings file that needs to be replaced or something like that. As I said before, I'm not keen to take the uninstall path as I imagine I'll lose the email account and files as well. Not "end of the world" stuff as I'm using TB as the imap client/ interface for email so can set it up again. But there's a bit of email to pull down or sync so prefer to find a repair. Hope some one can rescue me please. Which of the config files did I screw up please?? Hope this all makes sense. Lou S
