Yesterday I was trying to access My Habitat at Habitat for Humanities website. I spent almost two hours trying to connect, 1 1/2 hours on the phone with Habitat Tech Support. Ultimately, they told me to I had to use another browser. I had Microsoft Edge that came with my Windows 10, so we used that and I was able to connect. Another problem I have with Thunderbird is that since Windows 10 was installed, neither Adobe or Excel will go to Thunderbird if I want to email a file. I have a work around, but it is really annoying.
