Had to call the PAYPAL support 1-800 number because of a failed INR (dispute) refund that wouldn't process. (Pakistan this time)
Support person asked which browser I was using.
I was using Chrome.
They mentioned that Chrome is the least compatible browser for PAYPAL.
That was a surprise to me given what all I've seen on the boards.
The support person (as have all the PAYPAL folks I've dealt with) seemed to know their stuff.
Anyway I thought I'd post this informationally.
I'm still sticking with Chrome for now at least.
