I use Windows XP and thankfully never have had to contend with the “permission” issues introduced by the Vista and Windows 7 platforms. In both cases, you must tell Windows that you have the “permission” to change folders and files. If you search some of the forums where this is discussed, you will discover that few (if any) of those using either Vista or Windows 7 like this feature in the new platforms and often go back to Windows XP because it does not include this “permission” feature.
Here’s the problem: When you attempt to use ProAPOD in either Vista or Windows 7, the file is set by default to “read only” and as a consequence you cannot “save” your work. This is not the fault of ProAPOD, but rather the “permission” settings in Vista and Windows 7. As a result, you must first give yourself “permission” over the folder and files before you change ProAPOD from “read only”.
I wrote instructions on how to do this in Vista in the following article: http://www.proapod.com/Articles/vista-perm.html
Another site has posted instructions on how to do this in Windows 7 at: http://www.blogsdna.com/2159/how-to-take-ownership-grant-permissions-to-access-files-folder-in-windows-7.htm . This same site also provides a small file that you can download free that will enable you to “take permission” from a menu at: http://www.blogsdna.com/2173/add-take-ownership-option-in-right-click-context-menu-of-windows-7.htm. It appears to be solid information, but again, I do not use Windows 7 so I personally have not implemented it.
If you are encountering “permission” issues in Vista or Windows 7 I strongly recommend that you read these articles because I am not going to be much help to you. I know it’s a pain, but as one posting in a forum stated, it’s the reason why many have opted to return to Windows XP.
