yes, I've tried all those options, none work as expected.

A window is only ever covering part of the label. The bottom line of the label is always visible and that's what I want to hover over to have the rest of the label show up.

OnEnter and OnLeave do work. I've tested it with changing the text of a label. It changes the text to a test string on enter and changes it back on leave, as it should. When the always on top is set to true (on or toggle) though the entire label just disappears.

The problem isn't with the events, as even issuing the !labelalwaysontop bang command causes the label to disappear.

Any other suggestions?
