I have a simple problem using the ReplaceAll operator.
I am using version Mma. v. 2.04 on the NeXT  (however the same  
happens on the MIPS Mma v.2.0) with the following results

Sqrt[240] /. Sqrt[x_] -> 2 Sqrt[x/4]
4 Sqrt[15]

Sqrt[480] /. Sqrt[x_] -> 2 Sqrt[x/4]

Log[480] /. Log[x_] -> 2 Log[x/4]
2 Log[120]

This kind of thing really shakes me up.
