Here's beta.ee It has had the coding and html etc radically adjusted in an attempt at MAC compatibility for correctly 'populating' the dialog at its launch.
All users should upgrade - it has been tested on PC, but PC feedback would be appreciated if these changes have broken anything that used to work before [seems unlikely though].
Again MAC feedback appreciated [ ] - note that there should be a brief delay on a MAC as the dialog first opens - it might briefly show incorrect options checked... but hopefully then it'll revert to the correct 'default' values - this temporary delay is part of the testing... it's as if [unlike the PC] the MAC fails to wait for the dialog to be fully loaded before it attempts the populate it - thereby failing to do it - the short delay tries to avoid this...
