Content disappear after widget selection

Hi, since the last WordPress Update I can’t edit any content of my widgets. I can see the content in Appearance/Widgets but once I click on one of these widgets, it only shows the empty Visual Editor. I disabled all plugins except the Widget Editor. Same problem. Any ideas? Regards Lutz
