Python module problem.

I'm using lython linuxcnc module as stated on wiki page. But When i try to do:

c=linux.command()
c.program_open("something.ngc")

I got error: file is already open, can't open file (in linuxcnc main program).

When reading status:

s=linuxcnc.stat()
s.poll()

I always get M2 in command field (empty when machine is not running), 196 in current_line field.
I'm using simulator and need those values to control it.

After some testing i found that it gives command nad line but when doing line 102 it gives line current_line=2095 and command from line 3097. For 103 current line=2096 and command from line 3098 and so on. Strange behaviour.
