here's how I would do it
1) offer Vlad $ to add an additional field in the Tab Settings dialog for "Alternate Title", or a checkbox to indicate "Suppress title in favor of rollover text".
-OR- on the Tab Icon section, he could add a field for "Icon Title"
If that is prohibitive, then use JavaScript
2)
I'd leave the caption alone - Aware is defaulting the Tab Title to the Caption, but allows you a way to override that in the Tab Settings/Tab Title/Custom field. Problem is, if you put a space there, it ignores it and uses default. And you're trying to NOT have a Title, but you need some way to get what YOU want to be the rollover title into the code for JS to pickup.
I would put some "marker text" in front of the rollover title - in my case I changed it to "//RO Tab Title"
Then, some JS would look for the "//" and grab your title, deleting it from the Tab Title where Vlad put it, and inserting some html to set HTML's "title" field of the icon. Which is what I MANUALLY did in the 3rd image. There's no title text, but the <IMG> tag has 'title="RO Tab Title" ' added to it.
