CodeGear Delphi 2009 CPU Debug Window keeps coming

When i debug the cpu debug window keeps coming up. Most oft the time i'm
unable to debug.
Infos: CodeGear Delphi 2009 Version 12.0.3420.21218 Windows 7 Professional
64-Bit-Version(6.1, Build 7601) Service Pack 1
I allready tried:
Projektname:
(1) Backup all project files (2) Delet all projectname.* files exept
projectname.dpr (3) Build projectname.dpr new
System.pas
(1) backup system.dcu and sysinit.dcu out of the lib directory (2) Add
D-,C-,L-,Y- to system.pas (3) Start cmd and change dir to
C:\programme\CodeGear\RAD Studio\6.0\bin (4) use: dcc32 -m -y -z
..\source\win32\rtl\sys\system.pas (5) Move the system.dcu and sysinit.dcu
from source dir to lib dir
Non-User Breakpoints
Tools->Options->Debugger Options->Codegear Debuggers Ignore non-user
breakpoints -> check
Add to Regedit
HKCU\Software\Borland|Delphi\7.0\Debugging: EnableCPU (stringvalue):0
Change in Regedit
HKEY_CURRENT_USER/software/Borland/Delphi/6.0/Debugging/Integrated
Debugging = 0
.DCU and .DCP
(1) delete all .dcu and .dcp files (2) Build project new
Don't Use Debug .dcus
Project-> Delphi Compiler -> Compiling Use debug .dcus = false
Library Path make sure that you don't have the $(BDS)\Lib\Debug value set
in the Library or Browsing paths (Project->Options->Compiler); (Set it to
$(BDS)\Lib)
I have no idear how to reproduce this or how to fix it.
