Yesterday when I switched on my laptop, Dell Dock suddenly stopped working after I inserted a pen drive. It's not working since then. What should I do?
You need to completely remove the application from your system, then you can add it back to the system. On a side note, the pendrive shouldn't interfere with the dock application. You can download a new version from the application's page at Software Informer. Click on the big green download button and wait for the download to start.
