I have a form that is loaded through a hyperlink from another form. On this form I have placed a command button which closes the form (DoCmd.Close) I have also used the full syntax including form name and no save prompt. When i close this form using the command button I get a request for two paramter values that are used in queries in this form (I don't want this to happen) when I click the close button on the control box "X" this doesn't happen also it doesn't happen if I use file close. This problem only occurs on some of the slower machines in my workplace, any suggestions would be greatly appreciated. The is one combo box on the form in question which is set to run a macro after update, this macro requeries the 52 list boxes on the form.
