When I access a folder, I get for a few milliseconds the message at the upper left side of the page
"You cannot select this item"
See the screenshot, please:
When I access a folder in a network, sometimes this message stays visible and I get no access (even when I try again). When I log in (under the same account) from an other computer, I get access.
What can I do to avoid this behaviour? (I use 2.3 beta build #260)
