Xara slow to open

[masque]

Xara has always been a bit slow to open for me since the last couple of upgrades but I got used to it. As I've got a spare monitor I decided to attached it to my PC (i5 CPU, 16gb ram and some fans) to see if two monitors was anything other than simply being a bit showy. Since attaching the second display, one via HDMI the other DVI) Xara Designer Pro has gone from being a bit slow (30 seconds or so maybe) to click on the icon and go and cook a meal slow. Has anyone any experience with more than one monitor and has it affected Xara's opening times? I've tried telling the PC to ignore the second display to get back to normality and we are still in the two minute area to open Xara which is unusable. I should mention the primary monitor is now connected via HDMI rather than DVI as there was no HDMI connection on the older spare monitor. It hasn't effected Photoshop or Lightroom opening times or for that matter any other software in use.
