Found by Dell Tech support who Googled "double click search."

I then went to AllPrograms>Run, entered

regsvr32 /i shell32.dll

then got a dialog box that only let me click "OK", and problem is solved. Double-click once again opens folder, directory print function is still working.

Thanks to Dell tech support in Edmonton, Alberta.

Good luck.
