After litecoinz-qt launches it can freeze while the "Building Witnesses" process happens. There is no indication to the user that anything is happening, but the interface becomes unresponsive. This process can take several minutes, so it will make most users think the application has frozen.
Solution
Move the Building Witnesses process to a separate thread and add an indicator for it in the Information dialog.
