>It happens always. I never were able to see any message from Agent icon (when count > 0).

I did the test. Everything worked as expected. I enabled back a message to your account from the word searching. So, at that time, you had one message in the Last 10 word searching. If at that time a click is done on the Agent, it would give one message. Basically, when clicking on the Agent, it shows the list of the first one it finds. So, as the first one is Marked messages and no message was in it, it showed the messages from Word Searching, where in that case, there was one. Next, a click can be done on a message from the Last 10 word searching. Your account is set to put it off once the message is being viewed. So, when another click would be done on the Agent, at that time, you would end up with an empty list. All this is the normal behavior.

If you always get an empty list in the Agent, then there is definitely something wrong there as if the transaction would never hit the server and it would take that page from the cache.
