I have been using OpenLP 2.4.6 with great success. I set up a PortableApps USB with software that churches would need for Worship Presentation Overhead presentation. However, I found that when you eject the PortablaApps USB after using OpenLP 2.4.6 the USB will not eject properly - On latest Windows 10 update version 1909. Note, there are no problems that I could find with Windows 7. It works great on Windows 7.
I had to remove the "eject.exe" file in the Windows 10 %temp% folder almost every time I used OpenLP.
Here is a link for safely fixing the problem each time until Windows or OpenLP Portable has time to fix.
The change probably took effect with the wide deployment of Windows 10 version 1809, the October 2018 Update.

I'm adding this fix to my OpenLP training until it is fixed.
