the thing is for me i have 4 email address setup in zdesktop and atleast 2 others use images in their signature and they dont give any trouble what so ever.
After a few hours of testing and some advice from MMorse.. I backed up my email from that address and deleted the user and recreated it and the imported back my mail and it seems to be working.
Even thou it took about 2 days of troubling shooting...its working now. We couldnt find any errors in the logs to explain why it was hanging.
But if it happens again i will remove try what you did dcatenacci.
thanks for the response.
