I always have (alas) the latest version of either piece of software. Recently, maybe 1-2 weeks ago, LR started to have difficulties refreshing (repainting) its windows properly; I have to resize and maximize the app container window to get all frames properly back in place, otherwise it's like Picasso. And simultaneously, the icons for open apps in the menu bar get crazy, e.g. the poststamp-size window representing a running app would not appear on flyover, etc. The daate and time in the tray would disappear, then appear again, for no apparent reason. Unnerving, as a reboot seems to be the only cure. Any similar "user experience" ?
