Hi,
I have noticed this myself just a few days ago (Pd 0.52-1-really,
Windows 7). I had a quick look and couldn't immediately spot the
problem, but I will have a closer look. Actually, I have been working on
a branch with several scheduler improvements and this issue is
definitely on my to-do list.
