I have two PCs running the same config:
FM Pro 18.104.22.1683
Windows 7 Pro SP1, 64bit
Both are accessing the same DB from a server (FMP Host).
When the user exits the FM application and DBV, FM seems to close (nothing in the taskbar), yet FM is present in the Task Manager. That might not seem like an issue, but if the user attempts to open the launcher file again to that DB, there is no response. Nothing happens.
I'm getting the same behavior on both machines. The user has to force quit FM from the Task Manager for the launcher file to work. Note: I also created a Win shortcut that directs the user to the DB, but get the same behavior.
