my win98 system lost its folder association.  whenever i double click on folder, it opens the "open with" dialog box and it asks me what program i want to use to open SHDOCVW.DLL.  trying to associate it to the explorer did not work, neither did it work to re-install win98 on top of the current installation.  I would realy HATE to do a clean install, since it implies re-installing all the software i have installed over the last few years (since '95?).  In some cases, probably no longer possible...
 
Suggestions?
