When navigating around with Shinydrive your desktop seems to slow down and becomes unresponsive at times.
This could be caused by having Tomcat version 8.5.10 installed, Apache has a reported memory leak for this version of Tomcat.
Check your Tomcat version
If you have Tomcat version 8.5 installed, it is recommended to uninstall this version of Tomcat:
Backup your Shinydrive .war files in C:\Program Files\Apache Software Foundation\Tomcat 8.5\webapps
Uninstall Tomcat through Programs and Features
Recommend to download the latest version of Tomcat version 8.5, but Tomcat version 9 also works.
Put the .war files back into the web-apps folder in Tomcat.
