Arrow Exception:UI Engine accessed without holding the event lock

Please Login to Remove!

I have added a customer menu item(such as "Print...") to Browser.And I am expecting it will pop up a form to input some text after clicking this "print..." menu item,but I always get the exception:
"UI engine accessed without holding the event lock".

What is wrong.How to hoding the event lock?How to pop up a form after click the customer menu item?

Many thanks!

Default Use invokeLater(...)

invokeLater(new Runnable()
public void run()
// Code to pop up your form
