Edit: Seems like "multiple" in my case actually means >= 3
Comment 2 Albert Astals Cid 2009-08-24 01:06:14 UTC
Pino didn't we discuss this already and we came up with a locking mechanism? Or did never really implement it?

Should be in trunk (locked queue'ing system), will backport if stable enough.

This should have been fixed for KDE 4.3.3 (Okular 0.9.3).
If there are still problems, feel free to ping or reopen.
