Saving Projects

Well it's sort of normal behaviour for all software.. , If you choose "save as" your either going to save in a different format ,or, change the name.
You have the option of saving any given project as a BUN , CWP , template or Midi file.
If you use "save as"and don't change the name or the type then it is normal to get the "do you want to replace this file" message. This is true for all software. And it's also normal to then be asked to save the open project, word document, photo etc,, again when closing. 

thanks guys!
The replacement of the file is not the problem here, I do expect that prompt always and I do indeed want to replace the file. The prompt in question is the secondary one that asks if I want to 'save changes' to a file of the same name. This is always followed by (whether I choose yes or no) my having to rename an identically named file the next instance it is opened. This doesn't happen always but is almost guaranteed if I am working on a project for a considerable amount of time.   This is the same prompt one would expect if closing an application without saving first. It's just aggravating to have to rename files almost every time I want to open a project or bundle in progress.
I've never encountered a problem with any projects being bundled but will take that under advisement for sure. Thanks!
