When copy and pasting tables from another email and hitting send EMClient locks up and appears to get stuck in a loop eating away available memory until killed through task manager. I have also noticed EmClient truncating tables in forwarded emails only keeping the rows that are shown in the preview window (could be coincidental) and dropping the rest.
I am currently running version 5.0.18661.0 on Windows 7 Pro SP1
Any ideas what may be causing this or is there anythign I can do to help you track a cause down? Everytime I try to send out a project bill of materials I have to go to the gmail web interface to do so because of this. If I forget and paste the BOM into the email and hit send I have to deal with a database check due to the need to force close.
