Folks, there have been significant Flash upgrades lately. I bit bullet few days back, and uninstalled Flash, then down-loaded latest version from Adobe.
Numerous error/diconn events in previous 2 weeks at increasing rate prior to action; rock-sold WGT since then. I use Comodo Dragon for WGT and had Flash prefs set for 'notify me of updates' and failed to note any notifications.
Bottom line: clean up (clear browser cache AND flash storage) and and update your end of the game ... before getting on the 'WGT is screwing us' bus.
