windows 10 hotspot makes thunderbird and firefox freeze. Other programs continue to work as normal. I can kill firefox and thunderbird via task manager but the apps remain froze when starting back up. Need to reboot the PC and keep mobile hotspot off. Then all is well. Appears to be a bug. Microsoft just says stop using firefox. Have not yet tried that rather draconian option. They would probably advise the same if I reported it with thunderbird Please help if you can. I can use these programs on my pc without turning on mobile hotspot but it would be more convenient not to have to do so. Thanks John Verburg
