Cpu utilization reaches 100%

I am trying to send bitmap channel data to php script using loadvar sendand load. Before sending the data, i am collecting alpha,red,green and blue color value in a string. That is working fine. But before i set the string value to loadvar object cpu utilization reaches 100%. If m/c is idle in that point time then it working properly but if i am working on any other application then its showing a script is responsible for slowing down the flash player 9 and if u want to break the script or not?. If i click on yes then it stops , if i click on no then its sending value to php script and working fine. I want to remove that message. What is the way to do it? Actually the posted string is large and i cant make it small. Any help is appriciated. Thanks in advance. :):slight_smile:
