AXIIS Bug???

If you run a program without M02 at the end of the file AXIS does not respond to MDI comands any more. As i remember there was a message in prior versions of AXIS telling that "PROGRAM END IS MISSING" (or similar)
Now this Message does not appear, AXIS executes the program until the line before the last line and stops at this point. When i enter something like G01 X0 Y0 nothing happens. Axis returns to "normal" behaivour if i enter M02 in MDI.
Is there a way to change this? Or, show the message again, or tell the user that M02 is missing???

Regards, Thomas

Im running 2.3.1 and a file with %...%

The line before the last % is not executed and there is no way to enter MDI code when the program stops at this point.

if you enter i.e. G0 X0Y0 nothing happens. if you enter M02 axis responds again to MDI commands...

regards Thomas

Heres the code:
%
G91
F400
G0 X0 Y0
M8 (Coolant flood on)
G64 P1
G2 X0 Y0 I20 J0
M9 (Coolant off)
G64 P1
G01 X0 Y50 F400
M8 (Coolant flood on)
G64 P1
G2 X0 Y0 I20 J0
M9 (Coolant off)
G64 P1
G01 X50 Y-50 F400
M8 (Coolant flood on)
G64 P1
G2 X0 Y0 I20 J0
M9 (Coolant off)
G64 P1
G01 X0 Y50 F400
M8 (Coolant flood on)
G64 P1
G2 X0 Y0 I20 J0
M9 (Coolant off)
G0 X0 Y0
%

Well, i CAN enter something in the MDI edit-control, but i can NOT execute it, i mean the line ive entered in the MDI swaps up to the MDI-History but nothing happens until i enter M02. After that the MDI acts like normal...
