This is either an enhancement request or bug report.
Every time the Paragon Backup & Recovery 17 CE application is selected as the foreground app, or the window receives focus, typically by attempting to click a button in the window, the annoying "Check backup data validity, please wait..." window appears.

I must either wait for the window to finish checking validity, or cancel, then re-invoke the desired user operation/action.

This seems to be completely unnecessary.
Can you modify the app so that data validity is checked only once immediately after a backup is created (and only if the user selects the "Check backup integrity after creation" option)?
I can also understand the need to check data validity prior to restoring a backup.

But checking validity every time I click in the window seems completely unnecessary.

I have checked the "Check backup integrity after creation" option, because I want validity checked. But only once, immediately after backup file creation. Not every time I click in the window.
