Since my Winedt trial expired, I switched to TeXmaker. It's got a pretty interface, but needs some tweaking to make work right...for instance installing a dictionary...
I had a hell of a time figuring out how to make the Reverse DVI search work in TeXmaker. Here is the solution
in Texmaker Options>Configure Texmaker, replace the LaTex commands with
latex --src -interaction=nonstopmode %.tex %0 "%N%T"
This tells Texmaker to generate "source links" so Yap can link backwards.
in Yap click View>Options>Inverse DVI search>New
Give it a name, navigate to the Texmaker.exe file and add
be sure to INCLUDE the quotation marks or else it won't work (even though it lets you click 'ok' without them)
Set Texmaker as the default and you're done.
*UPDATE See the discussion in the comments section for some good suggestions
