I am the OP who started this topic and this is my fix.
The glass in my two windows was loose, not broken. My eventual solution was to order the rubber gasket or seal which goes around the glass and replace it. Easier said than done! There was no way to work the gasket all the way around the glass. Even taking the frame apart didn't appear as though it would help. The groove the gasket and glass fits in doesn't split apart.
My final solution was to work the gasket across the bottom of the glass and then use clear window sealant caulking from Lowes/Home Depot and squeeze the sealant into the gap between the glass and the frame on both the inside and outside.
To support and position the glass, I used a suction cup glass puller/holder like this: https://www.amazon.com/Qadira-Premiu...p+glass+lifter
First, it took over 30 minutes to work the rubber gasket across the bottom part of the glass. I didn't use the sealant across the bottom, but used the rubber gasket instead, because all the weight of the glass presses on the sealant and would allow the glass to settle down and leave a gap at the top.
After installing the rubber gasket, I used pieces of the gasket material to push in between the glass and the frame on both the inside and outside of the glass to center the glass in the frame. This is necessary so I could squeeze the sealant into the gap between the glass and the frame. After letting the sealant cure for about 24 hours I removed the small pieces of the gasket material and squeezed the sealant into the small gaps to complete the job.
