(I guess the assumption was that the application ID isn't dynamic, so the pointer would be to a compile-time constant string, so a copy wouldn't be necessary.) I think it should be safe to discard the string previously allocated... csApplicationFramework is certainly safe in that regard. For other code that may query the application ID ... you'll probably notice if that isn't. The proper way to deal with the application ID is to use GetApplicationName() every time anyway. -f.r.
