Encryption Catch 22

I have a desktop as my primary and a laptop as my "take
to a client's office" PC. In case my laptop is lost or
stolen I want to encrypt all my clients' folders on my
laptop.

Everything I've read so far indicates I can't copy my
clients' folders from my desktop to my "encrypted folders
laptop" modify various files, within the encrypted
folders, at a client's site, then copy them back to my un-
encrypted desktop and read them.

If I'm right, this makes sense from a security point of
view. I was just wondering if there is any way of solving
this problem other than de-crypting the laptop's folders
every time I come back home and encrypting them again
when I leave?

Not sure I follow you here.
If files are copied from the folder on laptop where
they are encrypted to a folder where they will not
be encrypted, while you are logged in on the encrypting
machine as the encrypting user, then the copies in the
folder not marked for encryption should be in the clear.
