When using the Type>Glyphs panel, it will show the glyph set for the last selected set. If I change the set to show, the set goes blank and no glyphs are shown. If I close and reopen the glyph panel, that last requested set will show. In other words, I have to open and close and open again to change the glyph sets that I want to look at. Maybe something for the developers to look at?

I have rebooted, I shut down every day. Resetting the preferences worked but what a miserable way to fix one problem and create ten more. Nothing is where I had it and I have to rebuild my workspace. I should have left well enough alone knowing how little I use the glyph panel. Thank you for the solution.
The preferences file is read on every start and is written whenever you shut down an application. It belongs to the most-used files on your computer. It is specifically at risk for corruption. It should not, but it does fail for this reason.
