Reviving this thread because I have the same issue, and it is not occasional, it's permanent. It happens with PP2010, 2012 and 2014. Reboots, SR upgrades, reinstalls make no difference. I've learned to live with it, but basically I've been spending a bit more time than normal on the forums so thought I'd look to see if it's just me. Well maybe it is, but that's beside the point...

oh, and it is across 3 machines as well, one a WinXP 32 bit, then I upgraded to a 64bit Windows 7 (i5 processor, laptop) to my current rig (i7 desktop) with Windows 7 64 bit.

Looking at the comments above I tried floating the paraments window and moving it to the second monitor. No difference, although what I did notice with these trials was where the param field shows up; dead centre of the monitor.

Any ideas how to put it back where it belongs?
