Hi Darrell, Ok, that explains it. The virtual Windows machine is using the Microsoft GDI driver which is OpenGL 1.1 (the graphics standard from 1997). I have quite a few bug reports that ctrl-click selection does not work with the GDI driver. This driver is used when Windows does not support whatever (usually ancient) graphics hardware you have, so all rendering will be without hardware acceleration, so it will be extremely slow. Also no modern OpenGL (like shader programs) can be used. I believe old Chimera versions worked with the GDI driver, but I’m not sure how old — maybe Chimera 1.6 or 1.5 before we started using GPU shader programs. It is possible that I can fix ctrl-click selection to work with the GDI driver. But I will have to think about whether it makes sense to work on it, since I think supporting long obsolete computers and poor virtual machines will take away time from doing interesting new things in Chimera for people who have suitable computer setups for doing graphics. There is no way around the broken selection when using the GDI driver that I know of other than using a very old Chimera version. Thinking ahead, we are working on Chimera 2, and it will require at least OpenGL 3.3 — it will not show or do anything on GDI graphics. So we are going to be setting some minimum graphics requirements for Chimera 2 that not all computers will meet. Tom

Hi Tom,
Thanks again for this great troubleshooting.
I've tested as you described and here are my results:
(1) Ctrl-click to deselect after a "Select All": this works as expected
(2) Ctrl-left-drag does present a box and does select whatever is enclosed in the selection box
(3) I don't have access to the actual Windows machine -- the RDS machine is itself a virtual machine.
(4) The results in the "Gathered Information" box reveal the problem: it is using the GDI renderer! (Full details at the bottom of the email.)
(5) Hover does not reveal any information.
This then begs the question: how to fix the problem? Do we just install a better OpenGL renderer on the virtual RDS? Are the following articles on the right track? https://www.vmware.com/support/ws55/doc/ws_vidsound_d3d_enabling_host.html http://www.phoronix.com/scan.php?page=article&item=vmware_vmwgfx_g3d&num=1
Thanks! Darrell

Hi Darrell,
When you ctrl-left-click in Chimera the mouse pointer changes to a hand with the index finger pointing to the left while you hold the mouse down. I guess that is what you mean when you say you see the cursor change to the hand. That would indicate that Chimera does get the ctrl-click mouse event. So one idea is that Chimera gets the ctrl-click but the x,y coordinates of the click reported to Chimera are wrong so it doesn’t select anything. As a test of this you could select everything (Select / Select All) then try a ctrl-click to select something and see if that deselects everything, as if the click was on the background. It seems unlikely the mouse pointer position could be reported wrong since that would probably make pressing on menus and buttons not work as well. Another test, when you ctrl-left-drag Chimera draws a green outline box — does that appear? Another idea is that Chimera gets the ctrl-click but in never gets the mouse release when it actually does the selection. Have you tested that ctrl-click select actually works on the Windows machine? If Windows falls back to the archaic Microsoft GDI graphics driver, then I believe ctrl-click does not work. You can find out what driver Chimera is using with Chimera menu entry Help / Report a Bug… under “Gathered Information”. One last thing to check. When you hover the mouse over and atom, a popup window shows the name of the atom. That uses the same Chimera code as ctrl-click selection to figure out what atom the pointer is over. Does that work?

Hi Chimera friends,
I'm using the Microsoft Remote Desktop Mac client to connect to a Microsoft Remote Desktop Server (an "RDS" running Windows Server 2012 R2). That RDS is serving out a Windows 8 environment and I'm running the latest Chimera release in it very successfully. Except that selection by picking (Ctrl-mouse_button_1) and centering (Ctrl-mouse_button_3) does NOT work. When I try to select by picking, the cursor changes from the arrow to hand momentarily. I also get this behavior when connecting to the RDS via any other client. Any thoughts on what might be happening and how to fix it?
Thanks, Darrell
