Problem with undo if i have any guides

Glyphs
1

if i have any guides then cmd+z works only on them, not on contours (and also ‘undo’ is inactive in the ‘edit menu’).
if i haven’t any guides, then everything works fine

i have 2.6.2 ver

thanks

Global guides? These belong to the master, not the glyph. Otherwise, glyphs have their own undo history.

That explains it. They go into different undo histories.
