Moved example to 1st post

Unfortunately for someone without much experience like myself the original example no longer exists to illustrate the context of the string inside ScriptClip() that could cause this problem. Are you saying string declarations inside ScriptClip() could cause this - care to elaborate?

In martin53's presumed absence, feel free to pipe up with an explanation, StainlessS or Gavino .
