I've just imported a big file from Quicken 2007. After some tweaking in Q2007 (changing the security types from Bond to Mutual Fund), everything seems to have come over intact.
With one glaring exception. If I look at the Portfolio Value graph, it has very dramatic spikes. During a roughly 5-year period, it changes by about 30% roughly every 3 months or so. Needless to say, this doesn't reflect reality, and if I make a similar graph in Q2007 there are no spikes.

I've looked at security prices and don't see any changes that would account for this. Does anyone know how I figure out where the error is, or how do I fix it?
Thanks!
