Problems on changing values in text-fields

I have the following problem:
When I change a value in a (text)-field and click directly after that to an ok-button CIS sometimes do not recognize the new value in the field.
the field have NO server-flush.
this problem happends in most cased when the mouse is moved during pressing the ok-button (this happends especially when using a notebook-touchfield).
it seems this problems occur more often, in a page with a lot of elements (up to 20-30).

Is there a solution for this problem?

Thanks
Andreas

…we tried our very best to reproduce. Could you provide an example (XML,Java) to us?
