GMan!!, Thank you for weighing in with seigneurial sagacity. This problem has been annoying me for over a year but rather than ask the dumbest question, I have been trying to sort it out by myself. The attachments and/or inline pictures (moving and/or still) come from different friends or acquaintances so I don't think THEY are ALL turkeys, and therefore it must be ME or settings on MY laptop. I am using Thunderbird 2.0.0.19 with Firefox 3.0.5 as browser, and there are three variations of the problem 1. an attachment with NO extension which I double click and gives "You have chosen to open <name of file> which is a application/octet-stream from mailbox://. What should Thunderbird do with this? Open with (Browse) or Save to Disc " I save to Desktop, where I double click and get "Choose the program you want to open this file <Browse>" I have tried Thunderbird/Firefox/Irfanview/WMV/PowerPoint/Nero Photosnap viewer/Windows Picture and fax viewer, ALL without success. 2. Some emails I receive have inline pictures and when I try to forward these to other friends, my Sent box shows the message as having gone thru but WITHOUT the pictures 3. Others with inline pictures which I try to forward, go thru with a border round where the picture(s) should be and have a) NO picture but tiny red diamond in the top R corner of each border, OR b) NO pictures but the border where each picture SHOULD be is picked out in pecked red line(s) I can send you privately examples of the above if you wish ( and if it would not be a nuisance) Perhaps I should sell my computer and take up rug-making??
