Sorry for the delay in responding but I had to take my daughter out to dinner - she just graduated from kindergarten!
Anyway it seems that the upper vista veiw windows are leaking as well as the main hinged windows are leaking as well.
I have removed 3 of the visata view windows and it is readily apparent that they leak.
Should I remove the interior walls to inspect behind them for damage?
The floors have suffered and I am replacing them. I am going to remove the refrigerator as well as the stove, sink, counter etc. all the way up to the center bathroom.
The rear of the unit seems to be ok.
Thanks for the help.
