I run Fedora Core2 Test3 on a PC " Intel PIV 1.GHz , 512 MB RAM , IDE HDD 10GB , nVidia Riva TNT2 VGA , 3Com 3C905 Network Card " . when I try to run Ethereal 0.10.3 and tick on the "Enable network name resolution" on the "Capture Options" , it will run for few seconds then it will stop scrolling the view of packets , then part of the display is blanked to white color , when I try to close it from the cross at the top of the screen it will take 5 minutes with no response then an error message will popup telling that " Window with the title " The Ethereal Network Analyzer" is not responding this window belong to the application ethereal (PID=xxxx , hostname=localhost) . Do you wish to terminate the app ...... "
Please note that I use my ISP DNS server IP to resolve the addresses of internet hosts , and I don't have local DNS server on my network . And Ethereal works fine when this option is not selected
