Bug 81983 [preferences] Disabling and enabling folding on small file takes forever
Reported: 2004-12-29 04:24:31 | Status: verified fixed

3.1 M4 Using enable/disable folding on a small CU takes forever. This is caused by the recent change to apply the preference to all Java editors. In another (hidden) window (Debug) I had StyledText open which (understandably) took long to react on the preference change. Non-visible editor's should not react to this change until they become visible.
