-X bug?

(I sent this to 'screen-b58hYvQMzLNTaRP2uSPg1g@xxxxxxxxxxxxxxxx' and got no 
response, trying
here)

$ screen --version
Screen version 4.00.02 (FAU) 5-Dec-03

I am no longer able to set the escape sequence of a screen session
with e.g. '-X escape "^Tt"' in version 4.00. Also, I think I was able
to do -X next or -X prev before, which don't seem to work anymore...
Can someone else reproduce this? Is what I'm trying to do still
supported?

Frederik
