Hello, having a problem using Thunderbird and sending outgoing email with signatures. Occasionally when replying to an email containing an signature with image file (company logo, jpeg format) I am finding that these image files are getting swapped and displaying the wrong company logo from some other email sender. This is a big concern for me as I deal with customers that that are competitors and cannot have this continue. Is this a possible cache issue that I need to look at? I am using Thunderbird 38.1.0 thanks Bud
