Anyone else been having a problem with {popup:text:description}?

I've just tried using it for the first time, with this.

Print Message:We hope your flight was enjoyable and you’ve arrived in good health, free of any cryogenic amnesia or coolant burns! Berg Imperial prides itself on providing excellent wellbeing{popup:*:As required by law and as long as persons adhere to their contractual obligations.

I get the hyperlink come up on my little star, which looks nice. But it doesn't do anything. I can mouse over and click it, but nothing. Nil. Zilch.

Further adding onto this, I managed to get it to work. Sort of. I think Popup refuses to activate when the game is in a state of get input.

There is a bug that stops it working in the short text contains any characters other than numberd letters and underscore.
