Actually, what happens when you use a portable copy and it wants to update depends on which browser you have set as default, and the choices made for downloads in that browser. Maybe it needs to be made clearer that portable copies use the download routines in the browser, not nvdas own download system as installed copies do. Thus, for example, if I use IE8, and select to run, then when its downloaded it will say, are you sure you want to run this software, and if i say yes, it will run the downloaded program and allow it to be installed or saved as a portable version etc. If I say save, then yes, it will save it to my default download folder and allow me to run it or not.
The installer as you know also allows one to run it from the temp or indeed any other folder its in, without installing or creating a portable copy as well.

So, its not as cut and dried and obvious as you might think here. to add what you suggest, will not convey the actual position to all users, as it depends on other choices made outside of nvda.

This could certainly be worth mentioning as a limitation of portable versions. I'll have to think on the wording, I can't come up with anything I like tonight!
