Delighted to hear that it worked for you.  Hopefully for others too.

I never searched for a solution.  I stumbled on it by accident because I just can't click fast enough to use the default setting!   The speed required was too stressful.  LOLOL!

Yes.

Sure.  Note that I have an old PS2 mouse.  Nothing fancy.

Double Click Time = 400-500 ms
Double Click Distance = 5 px

Well . . .  I have good news to report.  I have been unable to create an iso with refractasnapshot for a very long time despite excluding ALL of my /home directory because the iso were always too big.  So fsmithred and I decided to test your discovery.  He instructed me to change line 1010 from this:

 xorriso -as mkisofs -r -J -joliet-long -l ${isohybrid_opt} \

To this:

 xorriso -as mkisofs -r -J -joliet-long -l ${isohybrid_opt} -iso-level 3 \

It took refracta-snapshot-gui a very long time to copy and squash the files since I had deleted the work directory but eventually it finished with a 4.9GB iso.

Then it was time to try it in qemu.  I was delighted to see the boot process working as usual!!!

Now I need to redo the exclude list to include a basic home structure and perhaps delete a few things elsewhere starting with avahi.

I am overjoyed that I can now use refractasnapshot again.   And this is also a milestone improvement for refracta!  Thank you, thank you alphalpha!!!

Reality check . . . nothing lasts forever.  That being said, to date no posts have been pruned from this forum and would only be done manually with great care on my watch (which of course is also not forever for obvious reasons).

And of course read the Release Notes.

@thezeit . . . I sent you an email.  You might have it blocked

@thezeit  . . . Already being discussed.  Care to do more than suggest solutions?  Maybe roll up your sleeves and get your hands dirty?  We can always use more hands on deck.

Yes. We already are aware of that. There will be a way forward.

Thanks.  A link should be fine.
