left mouse not working in hotbox

[Anonymous]

I'm using Maya 2017 on Windows 10, and the hotbox will not respond to left-mouse clicks.  It comes up with the spacebar, but I can't select anything with the left mouse button.  The middle-mouse will work in the "quadrants" (selection mask, view chooser, etc.), but not the menus.  The right-mouse works everywhere, in the same way that the left-mouse should.

I should mention that this is on a laptop with integrated Intel 620 graphics...  Which I'm guessing is not a supported graphics option, but I've never had problems running Maya without a dedicated graphics card before, even on my previous, ancient laptop.  Also, I'm seeing the same behavior on two different, brand-new laptops - so it's not a mechanical problem.

Has anyone encountered this before?

Hi @Anonymous

Do you possible have another mouse to test with?

If not, you could try deleting your settings/preferences and see if that helps!

Let me know if anything changes!

These are both laptops, so there are no mice involved.  It's both the physical buttons above the touchpad, and the touchpad-click itself.  Attaching a physical mouse *does* seem to work, however.

I found some old threads on the Adobe forum that described a similar problem with Photoshop/Illustrator spacebar-left-click for the "hand tool".  The suggested fix was to disable palm rejection, but that doesn't seem to have an effect.

But as mentioned, my previous laptop (also a Thinkpad) had no issues under Win7, and the new laptops are different models of Thinkpad (an X1 Carbon and an X1 Yoga).  So the common denominator seems to be Win10...

After a whole day of searching & trying stuff, I think I've nailed it.  Windows 10 has a setting called "touchpad sensitivity" that supposedly rejects momentary touchpad contact from registering as tap-clicks.  For whatever reason, the result on my machine was that the left mouse button was disabled whenever *any* character key (so everything but ctrl, alt, etc.) was held down.  Maybe something to do with the interaction of windows and the Synaptics driver, which has its own palm-rejection voodoo.  Who knows.

Anyway, turning Touchpad Sensitivity to "most sensitive" re-enabled the left mouse button.  For good measure, I also disabled touchpad tap-clicking altogether, since I have physical buttons on my laptop and don't need to tap-click.  For the benefit of the next incredibly frustrated person, here's where to find it - it's at the bottom:

Thanks.  I've always thought of myself as pretty lovable...  But it's nice to get external confirmation just the same.

You're a life saver! I was having this issue on my laptop and the solution you described above was the solution I needed to allow me to actually click on the hotbox items. What a simple solution that costed me so much time and frustration! Thank you so much!!
