I second (I third?) this request.
I find it very annoying when a piece of software decides for itself how long I need to read a message. In fact, I'd like it to keep displaying the tooltip for as long as the mouse stays in position.
It's a similar issue to the Context Menu display time,
viewtopic.php?f=6&t=4032 which was resolved by a simple entry in Freecommander.ini
Any chance of a similar fix? I'd be much obliged.
