Windows 7: WM will not open eml. files filed in docs

I've done all I can so to set WM as my default, it says it's default, but when I try to open an email filed in docs, and I have WM set to be the default, the only thing that happens is WM which is already open pops up, but not the file I clicked on. I had to set WM back up after SP1 and I've done everything I could find on this board, but I'm totally stumped now. I've installed SetWinMailDefault, don't know for sure it went in, but I thank it did. What would happen if I used that again, or manually put it in the registry? Thanks for any help. Belle

If you have a copy of "setwinmaildefault.reg" you can right-click on it and select "edit". But I notice that this registry edit is quite complicated so it would be very tedious to check all the entries or to do it manually. You can double click the reg file again. You can also post your question on the Windows Mail Tutorial Forum. I imagine the people over there are dealing with Windows Mail issues which is why they are there.
