I've got a few clients using the Templates Zimlet now and loving it, however occasionally it forgets how to work, i.e. You try to select a template and all you get is a empty drop down bubble about 3 characters wide.

This only seems to happen in Zimbra Desktop. The only way to resolve the issue is to completely close ZD and then restart it again. After a session of doing templates 6-10 emails it will fail again requiring a restart.

Any suggestions on how to resolve this?
