Reporting old problem. Guide freeze for now reason. Can move guides in the neighboring glyph though.
Now idea what triggers it. I literally just opened the file and tried to move a guide…
Is there something else in the glyph like an image? Does closing and opening the file fixes this?
Yes, closing and opening works. No images, just paths and anchors.
This is still not fixed. There is no known trigger (to me) but sometimes guides just freeze. When I duplicate the glyph I can move its guides without a problem, original stays frozen.
