Error on wsterm2b

[SpellTrap]

I modified wsterm2b.ssl so that the shock floors and force fields would correctly deactivate, but now I'm faced with another problem. When I first enter the 2nd level, if I drag my cursor over the terminal, "Error" appears in my message display in the bottom left corner of the screen. If I drag the cursor over it again, it works normally, displaying "You see a terminal" or something like that. Could someone please check and see if this happens to them using the default wsterm2b.ssl? Any ideas what might be causing it (I'm sure it can be traced to a certain procedure)?

On a side note, what was the intended purpose of the trip wire on that level? I cross it: nothing happens. Was it supposed to have some effect that was never implemented, or was it meant to trick the player into trying to go around it, tripping the traps set up there before they noticed them.
