I expected a working product before you would offer it for purchase.
Fences 4 is available now at Beta level for people to assist in its maturity to full Level release.
This is commonly done to maximize exposure to as varied as possible systems/uses to eliminate bugs/issues properly prior to full release.
If one does not wish to engage in the testing process one should wait until full level release.
If issues are found it will only aid with the full release to post information of what is encountered with your system, along with details of the system [and OS].
Both the release version number and the word 'Beta' should be sufficient for people to understand that personal results may vary...
