I previously reported a bug in the Net Worth report that occurs when transactions were entered using the Misc. Income field and then assigning a Category in the "Category for Miscellaneous" field. The work-around was to make sure and enter Income Transactions using only the Div or Int or Cap Gains fields.
After installing the R5 update this bug is fixed. I didn't check to see if the update went back and fixed previously entered transactions, but I can confirm that it no longer affects new transactions.
In the release notes for R5 they mention that it fixed a bug related to "Misc Expenses"...either there was another bug I didn't know about, or the person who wrote the release notes was confused.
I'm running 2007 Premier on Win XP with SP-2.
