Just installed KSP 1.3.0.1804 en-us from steam and added the "KSP Français Patch" (still being developed) and ModuleManager.2.8.0.dll
KSP is installed in Program Files (x86) so thst's the 32bit version, I guess.
I started the game and my wife needed my help for something. When back, windows had switched the display off. Woken it up and the three kerbals were in EVA there but the usual Menu was gone. Aiming a click at the expected location for the first item succeded and then going back didn't even restore the menu. Screensaver was set to "Black" and password required to unlock.
Windows 10 / 4GB / 64b system, NVIDIA 650 GC, what else is relevant ?
I repeated the experiment and could reproduce the bug in the stock game, (having moved away the mod and ModuleManager to a directory on the Desktop)
I love the game and work with others towards making a good FR language patch / mod.
Have a screen capture but cannot see how to join it here.
