[H] bitlocker?

[Winterlight]

I want to use drop box to keep data on my laptop synced with my 
desktop. Things like my contact program, schedule, and some 
confidential info. It has to be encrypted in case it gets stolen. I 
set up a shared folder between computers within Dropbox, and the used 
Truecrypt to create a container that Dropbox will sync. However, the 
desktop leaves the container open 24/7 and can't be synced until I 
unload it, and reboot.... so this is'nt going to work.

I need a different solution. Would Windows 7   Bitlocker, on both 
desktop, and laptop do this by keeping the folder contents 
individually encrypted therefor allowing Dropbox to keep everything 
synced in real time? Or how else? thanks
