This is probably a rookie mistake, but I am having cursor problems. When using fireox or I.E. to compose a message the cursor appears for a split second in the TO: field, and then disappears. I have to click on the field to get it back.
Any ideas and please accept my appoligies if this is a rookie mistake.
update your profile to include your version (zmcontrol -v)
if i recall, this was a problem that a lot of people had because of an outdated com_zimbra_emailattacher zimlet. check the version of your zimlet and update if necessary.
