I have encountered following problems both in 1.6.1 and 1.7RC2:
1) While selected the Admin/General Preferences, it doesn't get
loaded on the browser and hangs time and again, disallowing the admin
to change the preferences.
2) While Admin/Wiki is selected, the Wiki Feature column on the left
is masked by the left panel with login block, disallowing the admin
to select the features. Even the navigation bars does not appear.
Is this corrected in 1.7RC2, scheduled to released July 19, 2003?
