Ok I made EI9 my default browser and I am getting access to your urls through your application.
However when I am taken to your links I also get a "Cant read value of HKCR error". Suspect it has somthing to do with file permmison or where my files are stored. No clue.
"Cant read value of HKCR error" tells me that it's not a problem of file permission. "HKCR value" has something to do with the Windows registry, and indeed, to launch a URL, I use a function called "wxLaunchDefaultBrowser", and the internals of that function determines your default browser by looking inside the Windows Registry.
I have no idea why, on your system, wxLaunchDefaultBrowser encounters an error. But one thing that I can do is to ask it to not display any error message. I'll do that with the next version. When it's released, you'll please tell me if that fixes your problem.
