.EXE file bloat?

Just noticed when I upgraded to the latest version - the exe file I downloaded was around 971kb in size, but the file it replaced was around 3.7 Mb in size. Seemed a bit odd, so I thought I'd mention it.

You original file was probably the standalone EXE distribution, which is encrypted using runtime compression (UPX). The EXE file distributed in instalation package is not compressed.
