DF4.0 is very slow to start on Windows 10
I recently upgraded v3.8 to v4.0 on windows 10. I have found that v4.0 is very slow to show its menu on a middle button click the first time after every time I restart the PC. On subsequent clicks, the menu shows up near instantaneously. I have since uninstalled v4.0 and re-installed v3.8 and the problem is gone.
