Roberto,
Unfortunately CVI does not re-open your workspace files in the order that you opened them. Instead, it opens them in z-plane order. Our main priority was to make sure that if a file was on top of the window stack before you unloaded the workspace, it should still be on top of the window stack when you reload the workspace, regardless of the order in which they were originally opened.
Thinking about this some more, we could have implemented the re-loading in such a way that the z-plane would still have been preserved, and at the same time opening them in the order in which they were originally opened. So this was an oversight...
You asked whether it is possible to have CVI not open the files at all. This isn't really possible for confined windows (released windows are never reopened). However, it is a fairly simple task to select Window>>Close All as soon as the workspace is loaded. <Alt-W-L> That will be equivalent to CVI not re-opening any windows.
