ok thanks think ive got it
As i Said you by mails. To make run Atomic.Fe as Shell.
Create a .BAT file like that:
Cd \
Cd AtomicFE
Atomic.exe
(adapt it to your folder configuration of course)
Put call it for example : Atomic.bat and copy it in your windows directory.
With REGEDIT edit the registry Key :
HKEY_CURRENT_USER\ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \Winlogon
Add or Edit the Key : Shell
And put Shell = Atomic.BAT
Now it should work.
If you are under windows XP , you have to change the way windows open session. to do that :
Control Pane ->User Account->Modify the way the user open session (or something like that, i have a french XP so i don't know what there on US version). Then Unckeck : Use Startup Screen. (or something like that).
Then you can eventually use the AutoLogon. Something to change in the registry, you should find information about that in this formum i think.
I did that, and it works for me.
So if my atomicFE is in C then may bat file should be
C \
C AtomicFE
Atomic.exe
and i then place this in C\WINNT folder
and put Shell = Atomic.Bat in the shell value
