In Windows, certain windows don't have the normal copy/paste clipboard functionality. This includes the Debug Console for the staff client, and any DOS/Command prompt windows, such as the one we tell you to use when pinging the server.
To copy content from these windows (for say, pasting into a helpdesk ticket), follow these steps:
Right-click on the title bar for the window.
You should see a context menu containing such options as Move, Size, Edit, Properties, etc. Choose Edit
You should see a submenu containing such options as Mark, Paste, and Select All. Choose Select All
After choosing Select All, press the Enter key
Then window content should now be in your clipboard where you can paste it into another application. This is better than screenshots.
