Resize sprites

["Otterman2" <webforumsuser@xxxxxxxxxxxxxx>]

Wow...its been a while since i frequented this forum....my director skills have 
become somewhat rusty to say the least....Anyways...heres my pickle.

 Im attempted to create a toggle button to resize a sprite to fill the stage. 
It works fine if its stationary but the problem is...it slides onto the stage 
over several frames and when i tell it to revert back to its original size, it 
just 'sticks' to that one co-oridate and does away with the keyframe animation. 
Is there a way of telling it to go back to its animated state. Hope this is 
clear

 property mysprite
 property  myORIGINALRect


 on beginSprite me
   
   mysprite = sprite(me.spriteNum)      
   
   myORIGINALRect = mysprite.rect

 end



     
 on mouseUp me

   if mysprite.rect = myORIGINALRect then -------NOT FULLSIZE
     
     mysprite.rect = rect(0, -1, 1024, 706)------GO FULLSIZE

     updatestage
     
   else
     
     mysprite.rect = myORIGINALRect ----GO BACK TO ORIGINAL SIZE
    
     updatestage

     
   end if
 end
