Thank you.

>>Hi,
>>
>>In my VFP 9 application I have a form with many, many controls and many features. Currently a user can only create one instance of this form. When he/she clicks on the menu to open this form, the program checks if the form is already instantiated, and if so, simply restores it.
>>
>>Bases on some new business needs, I am thinking of allowing the user creating multiple instances of this form. My concern is that multiple forms will consume memory and possibly cause the application to slow down.
>>
>>1. How can I control/determine how much memory is being used by multiple instances of a form?
>>2. Should this even be a concern with the computers these days having a lot of memory (2+ GB)?
>>
>>TIA
