Vista - Move to Folder command

I just upgraded from OE6 to WLM.

I archive/organize my messages in folders (1 folder per company) and have
hundreds of folders in my storage location.

The problem arises when I want to access a specific folder, for example when
using the "move to" command to archive a message: in OE6 I was able to "type"
the folder name when the "move to" window was opened in order to quickly
reach the desired folder; in WLM I have to browse through the folders to find
the desired one and it is very time consuming.

The same situation happens when I want to find a folder in the left panel: I
have to browse for it, instead of typing its name.

I'm loosing so much time that I'm considering switching to another email
client.

Your help would be highly appreciated.
