Need help with DRIVEBUTTONS and network drive

I have mounted remote network drive as H: letter. I also add to the dopus toolbar next button:
Go DRIVEBUTTONS=network

And I see this network drive. But when this network unaccesible I see button with red cross over it. I want to hide this button in such situation. Corresponding help manual I use:
Go DRIVEBUTTONS=online

But now I get ALL my drives visible (C, D, F) and disconnected network drive too :open_mouth:

What I did wrong and how me to show ONLY connected network drives?

Thank you for help.

Try Go DRIVEBUTTONS=network,online.

I tried this construction too. It works like Go DRIVEBUTTONS=network (also show disconnected network drive with red cross over it).

Probably this function just work improperly because in help manual said directly:

As a workaround try:

Go DRIVEBUTTONS=-CDF,network

This will exclude drives c,d and f.

Also don't work. Disconnected network drive will showed anyway.
