I have created an e-mail signature in a new e-mail, pressed Crtl+A and gone to the Insert tab and then click the HTML… option. In the pop-up window, I've then copied the html code and clicked cancel. Then I've gone to the Account settings and pasted the copied HTML code into the Signature text section and Saved the changes. The html e-mail signature is then appearing how I want it to look when I click on Write. Initially it was sending without any problem but after sending the e-mail 10 or so times it's started getting stuck with the sending message status saying "Sending" and the progress bar is completed but it never goes. If I delete the png file it then sends without any problems. The file is only 63kb so I dont see why it's getting stuck. What's going on?!
