A couple years ago I painted some of the window frames on my house. I scraped off all the old loose paint taking much of it down to bare wood. Then I sanded and primed with Sherwin Williams exterior oil based primer. The primer took an abnormally long time to try, a few days before it was totally dry to the touch. I gave it about two weeks before painting with Sherwin Williams exterior paint, a white Semi-Gloss. Now half of one of those window frames has the paint coming off in sheets. Everything else is fine, just that one half a frame has the paint peeling badly.
Should I do anything special or just scrape, sand, prime and paint?

Sounds like moisture.......the east coast has been wet for pretty much the month of June. Generally when the primer fails and peels down to the wood it can be traced back to moisture. As far as dry time for the primer this again is effected by the climate.....if its rains or gets cool in the evenings it can stop drying. We had a gentleman stain a deck with oil and called wondering why it didn't dry quickly but our evenings at that time were still in the 30's to low 40's which extended the dry time by days.
