It is more prevalent during winter, when the temperature is lower. This makes it easier for condensation. This is caused by a defect in the spacer between the frame and the window. The spacer is made up of desiccant which is highly absorbent and will absorb any excess moisture.

This can lead to moisture seeping through the gap once the desiccant has been saturated. This could lead to condensation and water in the gap and is very difficult to eliminate.

After the frame is cleaned and the rabbet has been prepared It's time to prepare the replacement pane. Find the height and width of the opening both ways, then order an item of double-strength glass that is 1/8 inch smaller in both directions. You'll also need to purchase glass points, which are made of metal triangles that help to hold the glass in the right place.

With the window sash off the way, carefully pry it off of the wood molding with a flat pry bar. It is possible to scrape off old glazing using a utility knife or chisel. Make use of the heat gun to warm any putty which isn't able to be removed easily. This will make it easier to peel off.

After the frame has been removed from the mold and the frame is pressed gently into the new glass in its place.
