Hello there

I have unbound form with 5 combo boxes bound to quries.

All the quries have parameters, which the parameters are name of controls in
the form

Sometimes when i close the form, and another form is being activated (it was
before the current form loaded) i get an errors of EnterParameter Value, and
the old form is being opend in normal size, and pressing OK on the parameter
value the form is closed

What can cause this problem?
