Login Problem - FileMaker doesn't accept correct password
I created a database, and created 2 accounts for it (not the actual user & passwords, but you get the idea).
1. User: Admin, Pass: 1234 , Access: full access
2: User: user, Pass: pass, Access: data entry
My problem is this: when signing in with either account, FileMaker keeps saying that the user & password combination is incorrect. I have to log in approx. 15-20 times, using the same user and pass each time, before it will accept them and open the file. This happens for both the Admin and user accounts. Also, I noticed when I enter the accounts and privileges, the password changes to a 20-digit string (which I can't see because it's starred out). Why is FileMaker changing the password?
Software: FileMaker Pro 8.0v2, OS: Win XP SP3, database is stored in My Documents folder.
