Slow Flexpendant

Used Software     : 5.13
Used Flependant  : Small Flexpendant  

Hello,

Does anybody know how I can find out why my application on the Flexpendant is very slow? By slow I mean when I press a button it can take up 1> seconds till the action behind the button is preformed The appl. is only 500kb big, I disposing all the data after using it. 

I have 7 Multitask's running in the controller. Can that be a problem? If I look to the processor it works on 26%, not much!

Thanks for the reply
