flash controls does not repond when parameters passed in loop

Question

I have a windows application having a flash control. now i need to display some text into each cell of this flash control (12 cells) which i loop and fill(using setvariable method). i call this fillflash method inside another loop where i print the text i displayed in the flash.  now my app becomes non-responsive either while filling the flash in the loop of fillflash method or when i call the printer to print (printdocument.print()).  but when i minimize and maximise my app window, my app becomes responsive. everytime to make my app responsive i am forced to minimize and maximise the app .  please help.....
