Edit E-book program crashes

RenniePet · 09-10-2023, 06:15 PM

Hope this is the correct place to post this problem.

In calibre, if I right-click on "EPUB" below the picture of my cover and select "Edit EPUB format" an empty window is briefly shown and then disappears.

The same happens if I use Windows Start and select "calibre 64-bit - Ebook Management" and then "Edit E-book 64-bit" (I assume this is the same program), again an empty window briefly flashes on the screen and then disappears.

The program did work once or twice a week or two ago, but now it always crashes.

My PC runs Windows 10 and is updated.

One possible source of glitches is that I have 4 displays on the PC.

Any suggestions? I would like to use this program to analyze why the format of my e-book (a conversion from Word .docx) is not quite right in certain situations.

Is it crashing or is it hiding off the edge of one of those four monitors. If you can see it in Task Manager try cascading the windows (right click taskbar option)

It is crashing - it shows up momentarily in Task Manager and then disappears.

Strangely, it worked fine when I first started it just now. But when I stopped it, and tried to restart it, it crashed, and several more attempts to restart it also crashed.

Does it work if you reboot in safe mode? Are there any entries in Event Viewer? What video card are you using? There have been issues with QT and various video cards/drivers.

RenniePet · 09-11-2023, 07:21 PM

Today it's working fine! (Of course ...)

The video card is an AMD FirePro W4100 from about 7 years ago.

I do also have a problem with Firefox, it tries to show its previous windows when started, and always fails and shows a screen with a button "Restore previous session". So I click that button, and then it works. Firefox apparently needs to "settle down" with one window before it's able to restore its windows to the four screens.

As for Event Viewer, I'll take a look the next time the Edit E-book program fails.

There is something odd about your system. FF is very stable.
Are your user settings shadowed on a remote (cloud, NAS) drive?
You might want to perform a System File Check

Code:

sfc /scannow

Thanks to those who tried to help. The problem has gone away - hopefully permanently.

As for my setup, one thing I didn't mention is that I'm using a program called UltraMon, which I installed when the PC was new seven years ago. I can't even remember why. I must have paid for it, as it's apparently not a free program.

Anyway, thanks again. calibre is an awesome program.

After reading up on it I'd uninstall Ultramon if it was my PC.
I've used multiple monitors (and projectors) on Windows from NT 4.0 to Win10, maybe over 25 years, and never needed such a utility. I admit that sometimes Windows is awkward for that, but can always be sorted.

I see no use for UltraMon.

I've had as many as 4 Monitors on my system. Standard Windows does well.
