wondering what I might have done?

[Karen Lewellen]

To be sure, my mac  experiences are far from  typical at the best of 
times.
However, a friend set up the Grammy's broadcasting online on the CITI-tv site 
sitein Canada.
all was grand, until the  program went silent.
chrome was in use, going busy, quite frustrating.
What does one normally do when getting a busy error?
