An "old" @DbCommand + a brand-new R8 Quickr integration

I am taking a looking to my e-mail box user interface, refreshing my mailbox soon after my Notes 8.0.1 upgrade.

I can see that there's a (new?) action button that can be used to save attachments to a Quickr place, I guess:


But when I try to choose the Preferences menu item I get the following error message:


And on the status bar I can see this message:

I guess that the "database driver" is about the "qkr" option in the @DbCommand: in fact I found a ndbqkr.dll file into the Notes client program directory.

I previously installed the Quickr connector on my pc and I can browse all my Quick areas with no problems.

Have you experienced the same problem too? Is there any workaround?

I wonder what is the reason to use a custom @DbCommand() instead of using a classic Java/LS agent that works with the selected document/memo.

Is that because the linked .dll take advantage of the Quickr connector, or the Quickr connector is not a prerequisite?

I hope I can put on a diet my mailbox, saving my attachments to a personal Quickr area ;-)


P.S.

I've always seen @DbCommand's with "Notes" and "Domino" driver options... This is the first time a see a "qkr" option. Today I've also found a post by Starfist about a custom @DbCommand() to run agents, using a custom "agent" driver name.
