I just reinstalled Oblivion + Shivering Isles. Patched it to version 1.2.0416 then installed OBSE v0019b and tested the game. Everything worked correctly.
After that I improved some settings with the program RadeonPro. I tested the game and everything worked just fine.
I then decided to install some mods but I noticed that every mod that uses OBSE does not work if I have RadeonPro running in the background

I first created a RadeonPro profile using oblivion.exe as a startup parameter, which disabled OBSE. After that I tried to select OBSE_Loader.exe as a startup parameter for RadeonPro which results in RadeonPro not working at all (OBSE does work in this case).
So I am wondering: is it possible to use RadeonPro and OBSE at the same time while running Oblivion?
and if yes: what am I doing wrong?

Thanks in advance for any suggestions and tips

p.s.
I have 2xHD5770. I use RadeonPro because it allows me to tweak some settings related to CrossFireX
