Different programming in Flash?

Hi!

I would like to ask if anyone noticed if there is a difference in code-handling in Standalone/WebPlayer and Flash export?

I have a code which at first runs well, then when i reset some variables, it goes crazy and handles the 'if' statements badly. It runs well on Win Standalone and WebPlayer, but not on Flash.

Here is a part of the code:

 if (Input.GetMouseButtonUp(0) && distance == 0) {
 
    var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
    if (Physics.Raycast (ray,hit)) {
         
      if(!first && !second){
         hitpos1 = hit.point;
           first = true;
      }
      else if(first && !second){
         hitpos2 = hit.point;
         second = true;
      }
      if(first && second){
          measuredistance();
      }
     }
 }
 
 function measuredistance(){
   dot1 = Instantiate(dotmodel,hitpos1+Vector3(0,0.05,0),Quaternion.identity);
   dot2 = Instantiate(dotmodel,hitpos2+Vector3(0,0.05,0),Quaternion.identity);
   distance = Vector3.Distance(hitpos1,hitpos2);
   linerenderer = GetComponent(LineRenderer);
   linerenderer.SetPosition(0,hitpos1+Vector3(0,0.05,0));
   linerenderer.SetPosition(1,hitpos2+Vector3(0,0.05,0));
   hitpos1 = hitpos2 = Vector3(0.0,0.0,0.0);
 
 }

This runs fine at first, it spawns the dots at the places i clicked, and measures the distance between them, draws the line, but then when i reset the variables 'first' and 'second' (they are boolean) with a button and try again, the problems begin, because if i click with the mouse, 'hitpos1' and 'hitpos2' instantly gets the same value. The variable 'second' remains false, but 'hitpos2' changes. I see that, because i have on screen display of the variables for debugging purposes.
