Right-click dragging kills app_server #2

Closed humdingerb closed 9 years ago

humdingerb commented 9 years ago

If you right-click drag a font, the font name becomes a tooltip following the mouse pointer. Release the right mouse button and the tooltip disappears. So far, so good. Now every time you left-click that tool-tip reappears, even outside the FontBoy window which is frozen.

Vulcan-Death-Killing FontBoy as often as not kills the app_server. From the syslog:

While there probably is some underlying bug in FontBoy, nothing it can do should crash appserver. Please file a bug there.
