This plugin looked very promising, since it is one of the few tool tips that allows us to place a module as well as HTML code. We installed the tool tip, but had problems from the start. The tool tip wouldn't position on the page properly, and anything under the tool tip was useless once you closed the tool tip box. We received some help from support, although it was vague. They told us to install a new file, and this broke the plugin even more. After that, support went quite for over 2 weeks, and we still haven't heard anything after several new support ticket posts!
Would love to see this work, but even the developer acknowledged there were bugs they didn't know about, which we brought to their attention! Wait for a more stable version or better support!
