When a older or a tab have items which can't be reached it is normally a USB drive or a shared network folders or a network drive. It takes very long time for DOpus to give up maybe 30 seconds, but I have and idea how to solve it in my situation and maybe others will like this too?
Would it be possible to get an event trigger whenever you are trying to navigate to a folder or a tab but the destination is not reachable? Getting this event maybe after 5 seconds sounds reasonable. By hooking to this event I can write a script that will issue a "Wake On Lan" command. If I can get in the event what was the target then I will know which server to wake up.
If it is feasible at your side, I would appreciate your collaboration.
