[moneydance] Unable to record 401K matching transaction reminder in 606

[Jeff DuMonthier]

I have a transaction reminder set up for employer matching  
contributions to my 401k.  The 401k account is set up as an investment  
account.  The fields of the transaction reminder are:

Account (popup menu in upper left): my 401k investment account
Date: (start date and every 14 days)
Action: Xfr
Check #: Dep
Security: N/A (grey)
Category: N/A (grey)
Transfer: Salary:Employer Matching
Fee Category: Investment:Administrative Fee (N/A really as there isn't  
a fee)
Shares: N/A (grey)
Price: N/A (grey)
Amount: (amount of matching)
Fee: blank (i.e. 0, I've tried entering 0 explicitly and it makes no  
difference)

This has been working years, but now when I hit the 'Record  
Transaction' button nothing happens.  The transaction is not recorded,  
the reminder is not dismissed and there is no error message or beep.   
I have tried deleting the reminder and recreating it thinking maybe  
something was incompatible with Moneydance 2008, but it didn't help.   
I also opened the 401k account register and used the contextual menu  
to create a new reminder with the 'Memorize' action using a  
successfully entered transaction, and that reminder also fails to  
record.  If that doesn't work I doubt it is anything I'm entering  
incorrectly.  Has anyone else encountered something like this?

I'm running Moneydance 2008 (606) on Mac OS X (10.5.2), Java version  
1.5.0_13
