BufferZone default programs include "chrome.exe" for chrome browser.
That means that any application with the name "chrome.exe" will be opened inside BufferZone.
You can edit BufferZone programs by double clicking the BufferZone tray icon --> "Edit BufferZone Programs"
Change "chome.exe" to the path for chrome browser (for example: "C:\Users\UserName\AppData\Local\Google\Chrome\Application\chrome.exe")
And from the only "chrome.exe" file will be opened inside BufferZone will be the one in the path you added.
