Scanreg.exe hangs while checking system.dat under MS-DOS. However, it handles user.dat without problems.
I was hoping to compact the registry with the /fix option but, for the moment, I am thwarted in achieving this ambition.
Norton SystemWorks 2003 and PC Tools Registry Mechanic 5.2 both check and correct the registry without problems. Windows 98SE works very reliably and quickly.
There must be a bug in scanreg.exe.
Owzat! On ya way, back to the pavilion!
