Ctrl-R not working?

Luckily for me I only 2 tasks enabled in the startup tab. (trackballworks and Windows Security Notification Icon)

And after 2 reboots where I disabled one, still no change regardless of which 1 is disabled.

I am getting worried that it might be malware or other corruption. I suggest you verify the windows installation. The tools to do that are sfc and dism. One usually starts with dism then uses sfc once dism declares that the install files are OK.

This guide should help.

Where are you seeing those startup items? In Task Manager/Startup?

One suggestion is to run MSConfig. Under the Services tab, hide all Microsoft services. Check to see if any of the non-Microsoft services is disabled. If so, make a note of those services for later. Click on disable all. Restart your computer and see if ctrl-R to restart calibre now works. This will let you know if a Microsoft service is the cause of your issue. You can now use MSConfig to re-enable all the non-Microsoft services and then re-disable any that were previously disabled.

Personally, I find MiTeC's Task Manager DeLuxe a useful thing for troubleshooting things like this.

.

DISM was clear and SFC found a few errors where some items Start Menu files (not Calibre) had security ownership issue. Now fixed.

So clean.
And had no impact on the issue at hand. Unfortunately.

I have a look tomorrow at this and will compare what runs in safe mode to normal mode to see which services aren't running in safe mode. Then I'll disable non Microsoft services to see if that is an issue.

[georgemk]

Right well I disabled all the non Microsoft services, rebooted and it made zero difference.

However the discovery that Calibre will always restart when you click the restart button in the Plugins dialog box does mean that there is a different code path for that restart compared to the keyboard restart or Preference menu. I had a look at the code but don't understand the code flow.

I'm leaving it here as it isn't essential but at least others will find this thread when searching should they have the same issue.

I'll just have to add a plugin if I want to restart

Try flipping one of the settings in Preferences->Look & Feel that requires a restart e.g. Show layout buttons in the status bar (needs restart)

That also restarts successfully.

So it is the keystroke method, the Preferences Debug menu and the restart icon on the toolbar that do not restart.

No, it's the exact same code path. Restart happens in gui2/main.py and there only, all the various restart methods simply set a flag that code checks.

Well the end result is different so the question must be why. Basically when Calibre asks me to click restart, it does; when I ask, it doesn't.

[kovidgoyal]

Since its not restarting because something on your computer is stopping it, the question is why is that something behaving differently.

[georgemk]

I cannot say why it behaves differently. Only that it does.

I appreciate that as you cannot reproduce it, it is impossible for you to go further.

It's not a show stopper in terms of functionality, just a curio.

[compurandom]

It still could be a race condition caused by background tasks made worse by low memory. Maybe when calibre asks to restart, the background tasks are in a state where they can exit quickly. Safe mode helps because there's less stuff loaded in memory, it's not any specific thing.

[kovidgoyal]

there's no race left. The namedpipe that is generating the error is now closed before even launching the new child process. it doesnt matter how long the parent process takes to exit.

[BetterRed]

If Ctrl+r and Shift+Ctrl+r are okay in Safe mode but not in Normal mode, that suggests to me that is there something running in Normal mode, that is not running in Safe mode. Something that acts on, but doesn't consume the key sequences.
