I tested this application on my two pcs, with identical result on both:
1- At a certain point, after a restart, the icon turns blue and does not allow you to do anything.
The services are started and automatically, but so everything has to be restarted several times manually until it works again.
Reinstall app solves the problem temporarily
2- When the icon is blue, the uninstaller does not work and you need to reactivate the app if or if.
3- The uninstaller does not work properly and stays locked during uninstallation, and it is necessary to give it to come out on the parta icon finish
4- double rules
