Dear Igor! I used Eye-One Match 3 and Eye-One Display 2 to calibrate my laptop display. Now, when I run executable slideshow created with v.5 latest beta or watch preview, it seems like in the beginning of the slideshow the created monitor profile is discarded and colors are displayed with the some sort of default colors. In the end of the slideshow colors turn back to profile again. It happens just in the last moment before slideshow ends or just before desktop is visible again. Initially I thought, that it might be related to ATI gamma problem (ATI drivers problem) referred earlier in forum. But lightness does not change. Just colors change. My laptop has ATI Mobility Radeon 9600/9700 series video card. Then I made test: Removed all profiles from laptop display color managment and run PTE v.5 slideshow - no change in image display during slideshow. Recalibrated display and problem is there - the created profile is not used by PTE. After careful observation, the problem exists also on my desktop with NVidia video card. Color profile is discarded both, on my laptop (ATI) and on desktop (NVidia) while executing PTE 5 slideshow. Because my desktop monitor without profile is much closer to profiled color, initially I did not notice change. But the change is there in both cases - on laptop and desktop.
