C# script run time error: Permission denied

Hi ,



I am getting the error "C# script run time error: Permission denied" abruptly when my code try to post an image in log using following code



      Log["Picture"](Sys["Process"]("iexplore")["Page"]("*")["PagePicture"](),"Capturing image, see the image captured in 'Picture' tab below.");    



 Most of the time above code work as expected but sometime it throws the error "C# script run time error: Permission denied" 

                                                                                                                                                                                                             

Please help us. Any help will be appreciated, Thanks in advance.
