Drag and drop PDFs in the Zotero Standalone middle pane
Is it not possible anymore to drag and drop PDFs in the Zotero middle pane? I imported a PDF and wanted to attach it to the respective entry but it seems not possible. I does not let me do it and I don't get the [+] sign that I get when I file items into folder on the left pane.
Firefox (41.0), Zotero & Zotero Standalone (220.127.116.11), Windows 7
Restarting Firefox and Zotero Standalone does not solve this.
Friefox - 41.0, Zotero 18.104.22.168, Windows 7
In the middle pane, using existing pdfs and existing parent containers, I cannot drag a pdf into a journal. Or a book. Or a freshly created, empty parent container.
I can drag a pdf into another collection though, i.e. into the left pane IF and ONLY IF it is not attached to a parent container. If it is attached, I'm blocked. If I try to detach it by dragging it out of its parent container, I'm blocked. The parents can be dragged around, the pdfs not so much.
This seems to be recent behavior, it was working two days ago or less afaik.
Update: Disabled LibreOffice Integration and Word for Windows Integration. No help. Same behavior in Windows 7 32 bit and 8.1 64 bit, different machines.
Turned on logging, restarted. Turned on logging again and checked the box that evidently means "Stay enabled after restart" and restarted. First two lines of 6724 read:
version => 22.214.171.124, platform => Win32, oscpu => Windows NT 6.1, locale => en-US, appName => Zotero, appVersion => 126.96.36.199
Find in Zotero://debug/ window appears enabled but nothing seems to happen when I click it.
thanks a lot.
