[Pharo-users] Hanging reference and sluggish image

[Alain Rastoul]

Hi,

I have a sluggish image due to some hanging reference on a big object (a 
BTree filled with test data) that I inspected with GTInspector, and 
can't get rid of those references.
Opening a PointerExplorer on this object show me lot of various 
references from GLMCompositePresentations,
GLMPanes, AnouncementSubscriptions, blocks etc.
Is there a clean way to reset subscriptions , announcers and 
GLMPresentations ?

Any help or suggestion will be greatly appreciated,

thanks in advance,

Alain
