EdgeDev Crashing / lock up when return to merchant sites from Paypal

Over the past months I had frequent Edge Dev lock ups in all kinds of use, just browsing, having multiple tabs going.  It seems to be less frequent now, but I have noticed the last few weeks and as recently as today, that it still locks up frequently when a merchant site sends me to paypal and then paypal returns me to the merchant.  I frequently end up at the merchant site page wanting me to continue or confirm the order transaction and the page and all tabs are locked up and frozen.  I have been able in, some cases, to click the red X to close the browser, then reopen EdgeDev and resume when the tabs and pages are restored.
