App freezes when closing file

[bloody mess]

On new desktop version I just bought , when I imported a file and changed mind and wanted to close out of program, it asked to save and i didn't want to so I clicked no but program stayed open. Had to force quit on my Mac.
Trying to close out of program, normally with any other program on Mac, I click once on app, with affinity need to double click, I right click and see the pix I refer to is still running so I click quit, should not need to do that since I didn't save in first place.How I delete the photo that was imported,also nothing was done to that pix, just picked wrong photo?

Why did you have to force quit the app? Was File > Quit (or CMD+Q) not working?

Are you maybe talking about right-clicking on the app icon in the Dock? If so, that will show a list of recently opened files, but they may not all be saved ones. Regardless, if you right click on the Dock icon, the last item shown on the popup list should be "Quit" if it is still running, the same as with other application Dock items.
