Hi Patrick...as this thread apparently got rather contentious between James and I, I have to aplologize, as I was afraid we scared you off forever. In my humble opinion, these widows have now attained a moisture level of less than 15% and because they will stay suspended up in the air in the hottest part of the house...they will probably never do any better. The good news is that fingi's and molds really need moisture to live, and as these frames are now what we would consider "dry" it's proably killed them. Now you need to arrest the cellular collapse of the wood fibers that are left,and bind together the remnants so it will stay intact, and injecting or treating with a "wood hardener" is a good bet, as I started out saying.Think of these products as a water thin glue that soaks into the soft areas deeply and quickly, bonds to the cells, and then hardens without shrinking thereby congealing the whole are into a now hardened state ready for the next step...being paint touch up if you so desire.If done carefully, this will not affect the existing finish at all...and is fairly straigh forward. I use large Veteranarian hypodermic needles for this type of rescue...which make a very minute puncture yet allow me to get deep into the softest parts, and deliver the liquid evenly from the inside out. There are solvent based and water based versions of these products and here are links to two of them. http://www.minwax.com/products/woodmaint/hardener.cfm http://www.right-tool.com/pcpetwoodhar.html
