Thanks for your reply. You should know, I am not a thief. I have found the plugin in the free extensions repository. If you klick the search button and write to the field the tooltip
word you should find the two tooltip soon.
About the technical details: I switched off the mt upgrade plugin, and the tooltip works fine. As I think it means that the tooltip is not compatible with mt 1.2.4. Do you have any plan to make it compatible?
