For the past week or so, my first ctrl-v often does nothing. So I ctrl-v again and this one does the expected paste. I haven't filed a bug because I suspect this problem is not Leo-Editor's but Ubuntu 11.10, or the Fluxbox window manager that I use, or the Clipman 1.1.3 (clipboard manager) that I use. I also don't know how to reproduce it, even though it often occurs.
Has anyone else been seeing similar problems?
