I have a working file in Archicad 17 that goes delirious in explore mode.
Archicad doesn't react to any of the keyboard commands, but instead decides to furiously spin the model. (It seems he points the camera upwards and does some strange fly mode)
I couldn't find any settings for the explore mode and can't think of the reason for this malfunction. I even tried re-installing Archicad, but with no result.
I can't imagine having installed a corrupt version of Archicad - I downloaded both and reinstalled both times from the official Archicad site, since I am using the student version software.
The only messy thing about my Archicad is that I have made the gentleman bilingual by loading the German library in addition to the English one. (But I doubt that should have an effect? I did it on my old machine and explore mode worked fine!)
The only thing is that I am now using a new machine (with better parameters). Windows 8 and Nvidia GT 730....
I was thinking the same thing or maybe failed hardware. Maybe post your computer's specs so we can see in case if there is something that's incompatible?
I was surprised to see that the video card in that thinkpad is a plain nVidia card and not a Quatro card. Other than that I didn't see anything obvious so I would start there and reinstall the video driver.
Explore mode is only active if your 3D view is Perspective.
You may be looking at an Axonometric view.
