I have just installed an evaluation version of LabView 2010. But, I notice that when I create a LV program and descend down a subVI (this is subVI is also created by me, not a reference to a library), it only opens a read only version of the subVI of which I descend to. The window title also shows the subVI descended is a clone version, not editable. Why? Is it because of it is an evaluation version?

The VI is Reentrant. Since many can use the VI at once it opens in read only mode and you only look at a specific clone of it.

But, I only have one VI opened. It is still opening up a read only version when I descend down to a SubVI from that the top VI that is the only one opened in Labview. How do you explain that?

If you are using a Project, try opening the sub-vi through the project, and not through the calling vi.
If not using a project, open it the traditional way: File>Open> browse to the sub-vi and select it.
Alternatively (and more simple) try ctrl-M on the opened clone to make it the master.
To check if it is re-entrant, in the File menu, select VI Properties> Execution
Look if there is a checkmark in the Re-entrant execution box.
It does not matter if you only have one re-entrant vi opened. If you opened if from the calling vi, it will be a clone. Annoying, yes.

Thanks, that is crystal clear.
