There's some odd bug in KDE that was troubling me, but I confirmed it was also present in MEPIS 12's KDE running in a VM, in that our distro .iso files are seen as text files, so if you accidently click on them, kwrite will start to open them. That'll slow down the system considerably, and possibly eat up all free RAM.
Other DVD type .iso files in the same directory are correctly identified as "CD raw image files", so I'm stumped. Maybe some web searching...
Oh yeah, a known issue with isohybrid files:

Hmmm--extracting the attached file and putting it into /usr/share/mime/packages, then running as superuser:
Code: Select all
update-mime-database /usr/share/mime
fixed it for new instances of Dolphin. I'll have to add that to the next respin.
