#2 100% CPU Lock Up When Editing URL with a :portNumber
In version 4.7.2:
To Reproduce:
1. Start NetTool and switch to the HTTP Client tab.
2. Start entering a URL with a :portNumber in it, such as http://dev.example.com:4557/public/swizzle-sticks.
3. Enter a user name and password under the Authentication tab, and choose "Use Basic Authentication."
4. [Send] to that URL. Then [Clone] it.
5. Attempt to backspace in the URL field and edit the address.
Expected Result:
You are able to edit the URL.
Actual Result:
Inconsistently, the entire URL is highlighted and the combobox locks up, pegging javaw.exe at 100% CPU until the process is terminated.
I don't think this is just related to using the HTTP tab with a request address that contains a port number. I get this constantly regardless. Here is the error I get occassionally when this happens:
