Idea I see two ways to go here: Either prompt user for path to Captures at Install. Or, make it an in-app Option. Background In most enterprise environments 'My Documents' is a network drive. Sometimes when switching between LAN and WLAN (docking and un-docking a laptop), Fiddler's Capture files become corrupt. This also occur if the computer reboots unexpectedly. Once the files are corrupt, they're gone. A few times I've been able to recover them using 7-zip. The current work-around is to re-assign the path with a registry hack. It works but it's risky and requires admin rights.
