SIMS Nova 6 on Dual Monitor

[cprelude]

I have a user wanting to run Nova 6 Timetable programme on her second monitor - She has a dual monitor setup with Primary monitor on left and secondary on right. When she tries to drag Nova 6 over to the secondary monitor it seems to only get a third of the way across then stops, and the part of the window in secondary monitor area becomes non-clickable, non-responsive. Windows from other programmes drag fine over to the second monitor but not Sims modules it seems. Anyone else seen this, and found a solution. Nb., this is on Windows 7, apparently was not an issue on Windows XP... Edited October 29, 2014 by cprelude
