Folders are not in the same window
I have a big problem. I tried to add something to right click menu for a folder. I clicked
Folder Options >File Types
Then I choosed "File Folder" file type and clicked "Advanced". "Edit File Type" window came. There were 4 actions (3 about winamp and find). I clicked "New" button. In "New Action" window I was asked for action (named Selam) and application (I wrote explorer.exe) for this action. I added my action. I also choosed "Set Default" for my action. I applied the settings.
And the problem: Now each folder is opening in its window although "Open each folder in the same window" is set. How can I set folders to open in same window again. Please help!
Note: I cannot remove my action from the list since "Edit,Remove and Browse in same window" buttons are inactive in Edit File Type window.
