coordinates problem when rotating 3D structure

If I load a 3D structure into MarvinSketch 16.4.25, rotate it in 3D, and then try to edit it, MarvinSketch thinks that my cursor is located in a different position from where it actually is. If I try to convert an existing atom to a new atom by clicking on the original atom, the new atom appears in a remote location; or if I try to delete an atom, I end up deleting an atom in a remote location. It seems that upon rotation, MarvinSketch is not updating the coordinates of the structure to keep them aligned with coordinates of the screen.


I think I've pointed out this bug in the past, but I just encountered it again.


Workaround is to cut the entire picture and then paste it back in, but that's a pain to do for every edit.

Dear Bob,


I can't reproduce this on my desktop. Have you used the applet when you've encountered this issue?


best regards,

I am using the desktop version on a Mac running OS 10.11.4. I'm attaching the file I started with. Rotate it in 3D, then try to click on a C with the C button activated.

Hello,


Thank you for your patience. We know what the problem is, and this issue exists only for the "Rotate in 3D" option accessible via the View menu. However, to rotate molecules you are better off selecting the molecule and then pressing space 3 times. That is the "real" rotation function (changing the coordinates), while the former one you can think of as to only change the view angle you are looking at the molecule. 


Best regards,

After I press space three times, do I have to say, "There's no place like home?"


Seriously, is there a reason for this difference in behavior between using the button and pressing the space bar three times? It's totally counterintuitive that there should be.

We are working on a solution that unifies the two behaviours in a more user acceptable way. Will keep you posted when ready.

The fix is out with version 16.6.6
