Bug: Microsoft Windows [Version 10.0.19044.1706] 64 bit, and current version of PortableApps,
Only a minor annoyance:
System Shutdown is prevented after apps update ended, until "Finish" button is pressed
Maybe unnecessary system modal dialogue box? (please forgive me if terminology incorrect)
One or more apps update is started, left running and user is doing other work in foreground.
In the background, the updates finish and the window shows
Your portable Apps have been updated and are available in the PortableApps.com menu."
"Finish" button is active.
User finishes their foreground work, selects system ShutDown, and gets the warning:
This app is preventing shutdown
Options: Shut down Anyway or Cancel
