Good morning,

I did as you suggested and ran Quickbooks in a private browser and it worked well - no waiting, no hangups.  So I went back to a regular Chrome browser and cleared the cache.  I am embarassed to say this, but ........ at the top of the screen when you are clearing the cache, is a box where you indicate the TIME RANGE you want clear!  I never noticed this before.  You know what the default choice is?  THE LAST HOUR.  That's it!  

So I cleared the complete cache (all time).  That solved it.  

Best,

Ellen
