Here is how to change the interest rate and credit limit in Money 2005 for a credit
card:
1. Go to Account Settings by right-clicking the account on the
account list.
2. If the Account Type drop-down is grayed out, disable online
access for that account
3. If the credit card is enabled for online access, disable that.
[M05]Banking->AccountTools->ManageOnlineServices. Click the credit
card account, and choose StopUsingOnlineServices....
4. Go to Account Settings by right-clicking the account on the
account list.
5. Change the Account Type drop-down to Bank. If the Account Type
drop-down is grayed out, you probably did not disable online access
for that account. (changing to Bank also seemed to work, but gave
a different setup)
6. Change the interest rate. You can enter the credit limit as a
negative value for "minimum balance".
7. Change the Account Type drop-down to Credit Card.
8. Set up the credit card for online access again if you like.
