Do you mean 'Options / Script I/O-Restrictions' ?
Its' set to   * Allow Read, Restrict Write

If I set it to   * No Restrictions    I'll get this errror message:
----------------------------------------------------------------------
Possible Parse Error: Cannot find file 'Test1.pov', even after trying
  to append file type extension.
----------------------------------------------------------------------
Parse Error: Cannot open input file.
Render failed
----------------------------------------------------------------------

And again if PovRay is still running it's working fine without any error 
message.


That all is confusing me...
Shouldn't 'Script I/O-Restrictions' only belong to script handling ?
But the 1st error message belongs to the picture file handling.
