[RP] rpws commands run from terminal in ratpoison, but not from .ratpoisonrc?

[fivesides]

Hello,

this command runs from xterm in ratpoison, but doesn't run if from 
~/.ratpoisonrc:
ratpoison -c "exec rpws init 4; rpws 1; ratpoison -c "vsplit"; rpws 2; 
ratpoison -c "hsplit"" &

I want to do the frame setting as described by that command on startup of 
ratpoison.

Thanks in advance.
