Muntins and Mullions
People who are familiar with windows may be familiar with the term "muntin." These vertical wood strips are used to separate window panes in traditional multi-pane windows. They are typically used to create an authentic look in older homes and are often required by city ordinances for construction or renovations in historical districts. Modern replacement windows typically make use of muntins to improve the appearance of the window rather than for strength and stability.

A mullion is the single vertical prop that holds the glass panes together in a multi-pane composition. This was an essential feature prior to the invention of glass manufacturing technology because larger pieces were nearly impossible to make. Today's windows do not necessarily require mullions because the frames are constructed of two glass units and then glued to one another. However, certain older kinds of windows have mullions to provide support and they are commonly used for aesthetic reasons.
If your mullions show signs of age they can be easily repaired them by applying a bead or two of silicone on both sides of the muntin. Then press it back into the frame. If you are replacing a horizontal piece you might need to use a copingsaw in order to remove the old muntin, and then make the ends of the new muntin with the help of a file. If you wish to blend in, purchase another muntin that is slightly different from the original.

However, you might need to test the vinegar on a few corners prior to applying it to the entire area.
If the corners are loose and a concern you should disassemble the whole frame to reach them and then follow the steps 3-8 to resolve the issue. If the separation is small and only on one side, it may be possible to let the joint open a bit by wiggling.
If the corners are completely broken you'll need a small clamp, wood glue, and needle-nosed pliers. If only the corners at the top and bottom are broken you can hammer a finishing nails (these are nails that are thin and a similar size to a head) into the corner to help keep it in place after the glue has dried. Be careful not to put the nails too close to the corner, or you may weaken it. You can also strengthen the corner with carpenter's glue and a hammer, or wood putty.
