nsbu crashes when using ups.com website

when using the cost calculator at www.ups.com. NSBU will crash. Only a restart will bring it back online. It is a repeatable problem.

https :// wwwapps. ups. com/ calTimeCost? loc= en_US&WT.svl= PNRO_L1

I am using Windows Vista 32,  Chrome Version 49.0.2623.112 m and NSBU 22.8.1.14.

This has been going on for a long time, at least over the last 6 mos or so.
