TCPIP 5250 session hangs

I've been having trouble running CA95 5250 emulation with a TCPIP   
connection.  When I run certain functions (e.g., WRKUSRJOB, DSPSPLF,   
etc.) the emulation session hangs in input-inhibited mode.  The output   
from the command is never displayed!  The interactive job on the AS400 is   
waiting for input from the device.  It appears to have processed the   
command and sent the output to the display device and is waiting for   
input from the display.

The emulation program on the workstation is not hung up, though.  I can   
disconnect and re-connect to get another sign-on display.  I can sign on   
and work without problem, if I avoid the commands mentioned above.

The odd thing is, the problem doesn't happen all the time.  Some days it   
never happens.  Another day happens the first time I run one of the   
commands mentioned above.

My workstation is running Win95.  It's connected to an Ethernet LAN.   
 There is a bridge to the token ring LAN which gives access to the AS400.

PS

I'm largely ignorant of networking technology, so please forgive if my   
descriptions of such are less than accurate.
