Blender 2.77 Bsurfaces add-on works with "d" key in Mac version but not on PC version I've tried out Blender 2.77 on my MacBookPro 13" screen and all works as expected. I moved on to my Asus laptop with 15" screen (with a better video display) and installed 2.77 also with the Bsurface add-on.

When holding down the D key to draw with the mouse, nothing is drawn.

Do you have any suggestions? I'm relative new to Blender. Thanks

I've done further testing and here's the issue:  One of my PC computers doesn't change the curser to a brush icon when holding down the "d" key.  (works fine on another PC - desktop instead of laptop, same manufacture: Asus.)  

When I remote into the Mac where Blender functions as expected, drawing is still not working, yet when I remote into the PC from the Mac, the drawing works as the curser changes to a brush.  I've contacted the PC manufacturer but they claim it's a software issue but they have offered to have the PC reimaged, something I already did and I have the same issue.  

This undocumented feature is unique because drawing works when I use the GreasePencil draw button, but doesn't work when holding "d", and only on this PC laptop, works fine on 2 PC desktops and Mac laptop, one uses Windows 10 as the laptop that has this issue, the other Windows 7.  I've tried different versions of Blender still same issue.  It would be nice to have a solution or even a workaround because currently this is just an inconvenience in having to take the extra steps to draw lines in Blender.

Anyone else with a suggestion would be appreciated.
I found a work around for the issue with the NX500 Zenbook from Asus not working properly with Blender when using the "d" key to draw with the touch pad.  It works by just using the touch screen.
