Fixed logic bug that caused DH-Grep-PM to abort if the 'Browse' button was pressed when the search path was invalid. The search path is now checked prior to starting the 'Browse'.

Fixed logic bug that did not allow search to start when the 'Start' button on the 'Search Parameters' dialog box was pressed and the 'Search Pattern' line was empty, but the files only option was also selected.

Added 'Hard code word wrap' menu item under "File" on the menubar. This option adds CR-LF pairs to each line in the display window to make the current word wrap permanent. This should make it easier to print the search results.
