then if these Computers are offline, or if your Network e.g. NAS is slow or off-line; FC start takes minutes! (FC is Not Responding)
because of "reading" the favorites folders.
The same happens when "customizing favorite folders", it takes minutes until the "define favorite toolbar" dialog pops up.

update: after doing more tests I can confirm that resolving "off-line" addresses leads to a delayed FC start, in my case it takes 4 min 30 sec. until the main window [gui] is displayed.
I have some tabs open in each panel but all tabs are pointing to local folders, so the problem is caused by the favorite folders.
Can anyone else confirm this severe issue?
