(Using the free version).
Here's another issue I've found...
I can import and apply a CursorXP theme, but it doesn't show up in the list of available cursors in the UI list. I know it's a beta, but this seems like an obvious requirement (imported themes should appear in the list of available cursors). Also, while the settings changes do apply, they don't show the imported cursor in the preview portion of the screen.
Also, since I was already running CursorXP, I had to explicitly kill it in order to allow CursorFX to work. Either CursorFX should automatically unload CursorXP, or, at the very least, it should present a warning message indicating that CursorXP should be closed for the new program to function correctly. The lack of *any* awareness at all is questionable.
I would also suggest that there be an option for directly importing an existing package (maybe even a drag and drop operation), as opposed to having to open the 'new package' editor, and incurring the additional overhead of creating a new default package just before opening a package to import.
Based on my initial assessment, I would say that this is a good 'alpha' release, with lots of potential, but it has a way to go before it actually reaches 'beta', let alone an official release.
