System locks up when I try to browse host files...
 

Whenever I get a "Cannot Browse This Host" pop up I can't do anything but quit the whole application to unfreeze.

It won't let me close the pop window from the title bar, and clicking "okay" does nothing.

Any clues?

Many thanks,
Dante

You could try adding more ram to LW. Highlight the LW app & CMD+I & increase the max ram.

A possibility but I'm not sure how well it'll work is to go to LW's menu Tools-Options & View & Popups & change the setting.
