When would the WyUpdate.exe change?In the FAQ on your website it says " You should not included wyUpdate.exe in your updates - wyUpdate self-updates". Please explain how wyUpdate self-updates. Does it look for a newer version on WyDay servers and then automatically download a new version when WyDay release the next version?
