Huge Problem(s) Please Help!!!!! Asap

i've just delivered my program to my client and there are 2 MAJOR bugs.

bug 1: the first time program is opened, everything works fine. it goes to the switchboard, etc., everything's cool. however, if he closes the program (i think he closed it using the red X) and tries to get back in, only one item on the switchboard shows up from that point on. the thing is, this problem DOESN'T HAPPEN ON MY COMPUTER so i have no way of even attempting to figure this out. the way i have my program set up is i have an interface and a BE and an .mdw file all in the same folder. i've created a shortcut that uses a workgroup switcher so that he can open the program and use it w/the .mdw file.

i have no idea what could possibly be causing this to happen. i would think that the switchboard would open correctly every time.

bug 2: this one does happen on my computer.

setup: i have frmCustomers (outer form) with sfrmJobs (subform) with a subform inside of that named sfrmFinances. Everything in frmCustomers works fine, and everything in sfrmJobs works fine. The primary key (JobID) in sfrmJobs is entered manually. After the JobID is entered, sfrmFinances is accessible. sfrmFinances' control source is qryFinances, which has a few fields from tblJobs (control source for sfrmJobs). frmCustomers is linked to sfrmJobs by CustomerID and sfrmJobs is linked to sfrmFinances by JobID.

problem: a new customer is entered in frmCustomers. a job number is entered for the new job in sfrmJobs (JobID). the user then attempts to update a field (any field, but for example, ContractPrice) and a window pops up and says, "Field cannot be updated". you click ok and it pops up again, at least 10x in a row. then it finally lets you enter data, but when you try to save the record, it pops up with another window that says,

"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."

excuse me?? how could there possibly be duplicate data??? the funny thing is tho, when the user closes the form, and then opens it back up and tries to enter financial data w/the same customer, it allows it.

???????

The first bug is more important than the second one, but any advice or ideas on either are EXTREMELY appreciated. thank you very much in advance.
