------- Additional Comments From truiken@gmail.com 2006-10-11 15:31 ------- Upon further inspection, the real problem is that the installer takes control the installer UI by running the command MsiSetInternalUI(NONE). It then calls MsiSetExternalUI(uihandler). We should be calling the external handler if it exists when we change media. I'll send a patch shortly.
