Thanks Phil I'll check that, but I found the following works: Scroll down to the URL:Hypertext Transfer Protocols, click edit twice and make sure the following is in the application used to perform action box: "C:PROGRAM FILESINTERNET EXPLORERiexplore.exe" -nohome The same applies for URL:Gopher DDE should be set to: "%1",,-1,0,,,, Application should say: IExplore DDE application not running should be blank Topic should be: WWW_OpenURL Mike Burgess MVP was kind enough to point out to me the other day that 'open in new window' is dependent on the following files, therefore you should ensure they are the correct version for your system, and correctly registered. Run the following commands from start/run. Run each line individually. After each run, you should see a short message stating the command was successful. The first command is the one most likely to work. regsvr32 Urlmon.dll regsvr32 Shdocvw.dll regsvr32 Shell32.dll (only applicable to Windows ME, Windows 2000 and XP - if using an earlier operating system, run regsvr32 shdoc401.dll) regsvr32 Oleaut32.dll regsvr32 Actxprxy.dll regsvr32 Mshtml.dll Some people have noted that replacing urlmon.dll or oleaut32.dll with the versions that came with their operating system has helped. I would not try this except as a last resort. I found that half way down the page on the link above. My associations were OK, but reregistering the DLL's did it. I'm working again :) Huzzah! later jb
