Upgraded to 7.2.197 today. Map shows just blue background with Radar. Win 10 (1809) 64 bit. Shockwave flash is enabled. Default browser is Firefox. Tried it with IE as default browser same result.
I’m having the same issues with the exact same circumstances
This issue should be resolved in version 7.2.199. You can either download it from my homepage here or auto install it by choosing “Check for New Version” from the Weather Watcher system tray menu.
This version 7.2.199 resolved my issue.
