![Guy Harris](/assets/img/avatar_default.png)
Currently Ethereal sets and uses a default directory for reading and writing, but only in some places. This set of patches extends the setting of the default directory to the -w option as well as the -r option, and causes all file dialogs to use and set the default consistently. (I haven't changed the Preferences/Printing/File dialog, though, as that's a special case.) There's also a fix for a bug where Ethereal was issuing the message "Ring buffer requested, but capture isn't being saved to a permanent file" even though a file was specified with -w. There also appear to be some other cleanups in his patch. svn path=/trunk/; revision=6238
