*BUGS* SoapUI V5.2.1 - bugs with "_" and case-sensitive URLs in HTTP URL entry

I've had a couple of issues with entering some URL's into an HTTP request step 

1. If you try to use a URL which has "_" characters in the FQDN of the host then the actual requests made are changed from "http://test_server.fqdn.com/rest-of-url" to "http://null/rest-of-url" and you get proxy authorization error messages or invalidhostname exceptions trying to translate NULL as a DNS lookup.

2. If you need to enter something case-sensitive in the URL then the first upper case letter is entered in lower case and the cursor position jumps to the end of the URL. So if you have "http://test_server.fqdn.com/sometest/webservice" and want to change the "test" to "TEST" then you move the cursor to the "/" and delete "test" and type "TEST" you will end up with "http://test_server.fqdn.com/somet/webserviceest". You can enter it correctly through the "Custom Properties" grid but not directly into the "Request URL:" box on the HTTP Request step dialog form.

These problems also exist in V4.6.4. I've only tried these two releases.
