It should allow you to shell out -- it sounds like 4dos is not swapping.
An easy test is to type 4dos at the dos prompt -- it will swap out
and tell you where it is swapping out to (XMS, EMS, etc.)

Try the following lines in your configuration:
In config.sys:
	shell=4dos.com /s:b /P
In autoexec.bat:
	set comspec=c:\4dos.com
	set 4dshell=/s:b 

The /s:b sets the swapping to what 4dos determines to be the best location.
If memory serves me right, the order is XMS,EMS,disk, no swapping. You can
also add parameters to the shell and 4dshell lines to set the size of your
environment, history, and alias.
If you only have 640k w/o any extended or expanded memory, I think it won't
swap unless you specify a disk for it to swap to.
