Hi,
i recently upgraded Nuxeo 5.4.2 (HF15 to HF25 + studio project) and there's something going wrong when trying to use drag and drop between the content pane and the navigation tree.
If i pick a file with the icon and hover the navigation tree, some folders do not turn blue (no DnD)
If a folder happens to "turns blue" and that i expand it in the navigation tree ... it cannot turn blue anymore
Sometimes all the folders and workspaces in the tree refuse to turn blue
Quite strange ... , no errors in logs or whatever
any hint ?
