Comment 1 _ rkubacki 2007-04-12 12:19:04 UTC

It seems enough to hold just weak reference to event

Comment 2 Quy Nguyen 2007-05-29 23:41:20 UTC

The MouseUtils class is used directly by the visualweb editor and causes a
fairly significant memory leak issue.  Since the visualweb data structures are
hierarchical (e.g. a page fragment is embedded in another page), multiple editor
TopComponents leak from the MouseUtils.tempe field.

Dafe will take care of this.
Thanks, Dafe.
