Trace reference shadowing

[Anonymous]

Hi, I have an odd problem this morning. The trace reference tool seems to be displaying 400x39.3mm to the southeast when displaying from one floor to another. Not in the correct location. I have tried restarting the comp; a different file; an earlier version of archicad and it hasn't fixed it.
Any ideas?

Archicad 15
Win 7 64bit
Dell Vostro430 8.0GM RAM, Intel Core i7CPu
NVIDIA GeForce GTS240 Dual Screens Dell 2408WFP DELLG2410

Not sure how it would have moved on its own, but there is the option to "Reset to Default Position" to restore it to its original position
