Because of this, screen-sharing capabilities are critical to resolving computer-related problems that people report. I once got a report from a coworker that he couldn't import a text-based configuration file into an application. I was unable to reproduce the problem. It wasn't until I had a screen-sharing session with him that I saw the problem. The configuration file extension wasn't correct. It looked right at first, but then I realized that it had an extra .txt at the end of it that was being hidden by Windows. The application saw the .txt at the end of the filename and rejected the file. Nothing wastes time like emailing/texting/chatting back and forth when a voice call and screen share are available.
