Mac OS X 10.5.8

Nothing happens when I select Impose, Preview or Properties.

Also, not sure if it's a related issue but, I get a similar problem when defining Job Properties for hot folders in EFI Hot Folder Console. I click and nothing happens.

I have tried different versions of CMS 5. I have uninstalled (several times), reinstalled (several times), changed install locations, repaired Mac OS permissions, rebooted, powered off then back on, all to no avail.

I suppose I can resort to installing on a Virtual Machine.
