Designer crashed on Brush export, now it won"t close in Affinity on Desktop Questions (Mac and Windows) Posted December 24, 2018 Hello, my problem with Designer is nearly same. I can't close the program and I can't figure out why. If I try to close Designer, a message appears with a hint to close a file which is still in progress. But no project or file is open. So it is very frustrating to read lilbudda's experiences. It seems so I have to do the same steps, because it wasn't enough to delete Designer, clean up registry data, reboot and install again. Hmpf.
