Fixed

I realized fairly early on that the issue was related to something in the HTTP format. Through some manual trial and error, I was getting a 400 Bad Request message. I figured that maybe Windows was causing an issue in an attempt to protect, although I was pretty sure I had turned off all AV and firewalls. No luck, so I broke out an old 'Vista' computer and imaged it to Windows 10 Home, but without letting Windows do any updates and no AV or firewall active. Installed B4J, libraries, dependencies, jdk, etc. You can likely imaging my red face when I got the same blank window when running SendFunds .... no errors ... just nothing. So anyway, I thought, let me look back at the libraries. I realized that
@Erel points out in the very first posting on Web3 that OkHttp is a required library. In the post, it says
(internal library) after the link, and when I clicked on the link (many times), nothing happened ... so, I assumed
internal library meant I don't have to update it ... my bad. What was happening is Windows was actually blocking the download of the OkHttp 1.5 download link, so I right-clicked it and then I got the 'protective' message from Windows asking if I want to 'keep' or continue blocking the download. I of course downloaded it, then expanded the zip into the Libraries folder. Restarted my testing and everything works as it should. I went back to my new Surface laptop with Windows 11 and the process worked there as well.
