All of a sudden I seem to be unable to ungroup a set of objects which have been grouped previously, either by me, or as a symbol.



Also cannot group a set of objects which I select when in the unlocked mode.



What am I doing wrong? Is it an issue with layers? I don't remember having this issue before.



Thanks.

This is normal behaviour.  A symbol is not a group and cannot be ungrouped.  A symbol always behaves as a single entity except when Unlock is checked.

Only groups can be ungrouped.

Kind regards,
