For me the past several months the game consistently freezes with my avatar frozen at top the of a swing usually after playing more than 18 holes but sometimes fewer . I submit an error report most every time the game freezes. No problems submitting the error report with the game frozen.
My solution is to just refresh my browser and get back to playing.
WGT stated they believe this is a memory leak issue.
Before playing any multi-player game, recommend refreshing or
restarting your browser to decrease the odds of the memory leak getting
so bad as to freeze or crash the browser or flash.
