Just to update... I installed my full version of MSM SB and this is still going on... I'll check it again in January to see what happens...

First Problem: I have my paycheck and all of the included deductions (taxes, insurance, etc) set up for every two weeks. I got paid on the 5th and 19th of December. When I edit my plan, everything looks right - it allocates the correct $'s to each category based on how many checks I receive in each particular month. When I view my budget progress for December, though, it has both checks' deductions spent, but only one check's deductions budgeted...

To illustrate using nice round numbers:
**Monthly Budget: (for a two paycheck month)**
federal taxes: $600
soc sec taxes: $200
medicare taxes: $100
health insurance: $300
TOTAL: $1,200

**December Budget Progress:**
federal taxes: $300 budgeted, $600 spent
soc sec taxes: $100 budgeted, $200 spent
medicare taxes: $50 budgeted, $100 spent
health insurance: $150 budgeted, $300 spent
TOTAL: $600 budgeted, $1,200 spent ($600 over budget)

There are only two reasons that I can think of.
1) I set up my paycheck in MSM between 12/5 and 12/19 and it may see 12/5 as a regular split transaction but 12/19 as the first real paycheck...
2) I'm using the trial version of MSM (I received the full version yesterday and will install tonight)

I have a hard time believing that #2 is the cause, but I'll know tonight. If #1 is the cause, then I should be able to tell on 1/1/04 when the December Budget Progress turns into January Budget Progress. If I have all the deductions from all three January paychecks figured into the January budget, then I'm in good shape...

Does anyone have any other ideas?
