PS 26.3 hangs when saving PSD as GIF

[adpremxxx]

Lately, whenever I try to save a PSD file as a GIF, PS just freezes. I have to use Task Manager to kill the PS process and start over. I finally have to give up and use a free on-line converter. I've made thousands of GIFs like this over the years I've used PS, and never had a problem until the last year or so. What's changed? I've tried fiddling with some settings but nothing has helped. Am I the only one with this problem?

@adpremxxx try manually resetting your Photoshop preferences

Remember to back up your settings before doing the preference reset

If that doesn't help, can you post your Photoshop system info, in Photoshop go to Help > System Info, hit the copy button and paste the entire thing into this thread

Ged,

Thanks for the suggestion -- manually resetting PS preferences did the
trick. I don't understand what would have caused this, since I don't recall
making any changes to preferences around the time this began to be a
problem.

Thanks,
Steve
