In all nightly build, now im use 10595 for Windows, in batch build.
c:\CodeBlocks\codeblocks.exe -na -nd -ns my-workspace.workspace --build --target=Release
after some time codeblocks sleep, and build sleep, CPU use 0%
Helped expand main log GUI window, and mouse move on it - then code block continue build.
Reproduced on different windows 7,8,10 and different nightly build.
