Hello.
I don't know if it's just me or if I've missed anything, but the 'shell context menu' settings just won't 'stick'.
To be more specific, while the checkboxes in the Options menu stay ticked, they're not (really) doing what they're supposed to do. Sometimes they work, but only for a short while after I confirm the settings.
I checked all except the two 'email' options (Compress (to Archive) and email). And after awhile (I don't know how long), some options go missing. Specifically (if I'm not mistaken):
Extract files...
Extract to folder
Add to Archive
and even then, the remaining options usually only work a short while after confirming the settings. Right now, however, they won't work at all.
