+SPR# SLAE7W6GUE - Mac OS X 10.6.2: Fixed a problem that only happens on Mac OS 10.6. If a user opens MIME mail from the inbox and presses the ‘esc’ key to close the email, the MIME mail and the inbox itself will be closed. With this fix, only the MIME mail itself will be closed after pressing the ‘ESC’ key. This regression was introduced in 8.5.1.
