That is the way I have had the edit.
Code: Select all
<action>rxvt --hold --title \"pMount - $(gettext 'Puppy Drive Mounter')\" -geometry 80x10 -bg black -fg green -e fsck -Cv \"$ONEDEV\" &</action>
Are you getting it to do a file system check?
If yes.
I am using a save that has had software added to it by using synaptic package manager.
I will do a clean no save boot and see if it is still not working.
Someone posting in another topic, found the issue, so I tried and got it also, so reported it to you.
Update:
Now very, very, sorry I even said anything about this!
With a clean boot and using a new save with nothing new added.
It is working to check file system on partitions not mounted.
Now I am going to have to find what is braking it in the old save. 
I hate it when a save is causing the issue!
This old one has some good stuff in it that I really want to keep.
I may just keep the issue.
Never really used Pmount for this check anyway.
Maybe I will figure out something and at least be able to help the other person, having the same issue with Pmount.
Again, very sorry making you have to deal with this!!!
I am loving the changes you did make with BookwormPup64 10.0.7! 
UPDATE to the UPDATE:
It seems to be all about what mouse click you use to bring up the selection menu and also use to select.
Bring up the selection menu with a left click, then select file system check, by also using the left click.
It works.
If you use a right click to bring up the selection menu.
Left click on the file system check does nothing.
Right click on file system check and it works.
