Hi there, When using Merge to HDR Pro in Photoshop CS5 on my MacbookPro I can't see any 'OK' or 'cancel' button when dealing with the HDR Pro window where you can choose to remove ghosts and everything else. I'm stuck in that window and cannot navigate away without having to force-quit the application. I also can't chose to 'uncheck' any photo's like you're meant to be able to. I have a mid-2009 2.66GHz MBP with 8 Gigs of ram and 400 GIG free for space. I know this is specifically a mac problem as my pc runs it fine but I'm having to use macbook atm. Note: I saw a thread with the same problems as mine dated 2007 with no real explanation so I thought I could make a new updated one as it's still a problem. If anyone has any ideas I would love to try them/hear them. Cheers.
