Hangs on startup with "rainbow circle" about 1/2 the time on MacOS

[pointy]

xnviewmp 1.5.5, MacOS M1 Pro 13.4.1

About half the time I try to launch xnviewmp, the program hangs immediately. I can "force quit", remove my .ini file, and then it starts up.

I'm not doing anything weird, just an ordinary MacBook with a couple of attached USB drives (and I only really use one of those, and that occasionally). I have no idea what could be making this happen, but when I say half the time I mean it. It doesn't do that *sometimes*, but I've pretty much come to expect that I'll have to force quit, remove the .ini file, and try again.

I've searched for this issue but found nothing helpful other than "try removing the .ini file", which as I said does work, but I don't understand why it's OK that the program creates the very .ini file that's going to make it hang next time I start it up.

I'd be delighted to supply any sort of debugging information that might be available, but I have no idea where to find that.

Here's what I see in a terminal window when I launch it from the command line (the last bunch of messages):

Code: Select all

It gets to that "sizeHints" message, and then the "wait" cursor turns on and that's the last I hear from it.

do you had same problem with previous version? In '/Volumes/Macintosh HD/' do you have video files? When it works if you close XnView in a folder with only jpeg/png files, same problam next time?

Yes, same problem with two or three previous versions.

In the top-level "Macintosh HD" (main system disk) directory, there are no video files. On the entire volume there are probably some video files, I'm not sure. I do not try to use Xnview for video.

if you try to open a file from another folder, and start browser?

The problem is that the hang makes it impossible to use the application at all. I cannot select *any* directory; all I can do is force-quit the application. If I try to start it without deleting my .ini file, it will hang again.

[xnview]

you can try to change PathBrowser from xnview.ini

Can I tell it to not save anything at all in the "History" list? I've suspected that the problem might have to do with using it for images on SD cards that later are ejected. However, I have determined that hanging does not depend on that being the case. Still, I don't really need the history; I am fully capable of navigating on my own

If I clear both "History" and "PathBrowser" (which were both set to only the main drive, /Volumes/Macintosh HD), it starts up correctly without hanging.

as soon as you use a SD card, you have the issue?

No, that was a suspicion but by being careful I realized that SD cards being mounted and unmounted has nothing to do with the problem. For example, I do not have an SD card in the computer today, and the program had the problem this morning (until I cleared "History" and "PathBrowser" in the .ini file).

as soon as you clean History & PathBrowser, no more problem? When you have the problem what do you have in these field?

I have `/Volumes/Macintosh HD` in the "PathBrowser" field, and a random list of directories in "History".

Note that in all other respects my Mac is working fine. I don't have random hanging problems with any other applications. I am on the computer literally all day.

If you clean only PathBrowser when you have the problem, is it enough?
