Thanks to Tom, Dick and all who offered suggestions, but nothing seemed to cure the problem. As a last resort I began troubleshooting the PC by disabling all startup programs and selectively disabling non-Microsoft services installed at boot time. Although time consuming to re-enable them (services) one at a time, reboot, and then test for the problem, it finally appeared that a Malwarebytes Pro service was causing the problem. An email to their support yielded a quick response with a suggested fix to do a clean uninstall, reboot, then a new install. They provided the software to make sure it was done correctly. Lo and behold the problem is now gone. I can only conclude that there must have been some corruption involved and a clean install corrected it.
Thanks again to all. 73, Mike W0AG On Wed, Jun 28, 2017 at 12:09 PM, Tom <[email protected]> wrote: > As Dick mentioned this is the most likely reason.
