Are you having the same problem with LW beta 4.11.4? Off-hand I'm not sure what the problem might be.
I've searched the OSX sections of the forums & came up with these: 1.
Click on link 1, & 2.
Click on link 2, & 3.
Click on link 3,
& 4.
Click on link 4
Go to your Utilities folder & open Console & look for LW log reports & post one here. That way we may be able to find what the problem is.
