I'm using Photoshop 21.1.1, Mac OS catalina 10.15.3
I've seen here that there have been similar problems in Illustrator.
I use Export > Save for web and often have to save files with names that are long numerical codes, which I copy from an Excel document. Recently this has stopped working, and I have no choice but to type out these codes when saving the file - clearly unworkable. I've tried copying the text into a simple text editor and then trying from there, but nothing works. Even tried manually using the OS menu rather than using keyboard to paste, but no luck.
Is there a different way I should be exporting my files for web to enable me to copy and paste the file name in the dialogue box?
Any help greatly appreciated!
