Hi Jiwek, I searched my ntoskrnl.exe, which is version 5.1.2600.5512 (XP Pro SP3) for the relevant values, and found the ones at the following offsets are working for me: Top of bar: 31af0 34b00 34b8c Bottom of bar: 31b6e 34b82 Palette: 75d08 Maybe you could change the thread title to indicate that the SP3 values are in here too by now ;-) Cheers, Gerwulf
