Bug 8686 Type Hierarchy: no methods shown
Smoke for build 20020129 - open type hierarchy on TestCase - switch to Subtype hierarchy - observe: you don't see any members of TestCase - lock the method view observe: now it is impossible to get the members back. You can click on any node in the upper class pane. You have to unlock the view
