A7721 keyboard on a Mac – Command and Alt don't work together

[Matthew_Charlesworth]

On the left-hand-side of my keyboard, key commands don't work that require a combination of Alt and Command. For example, using InDesign Command+Alt+Shift+V is paste in place; and in Powerpoint Command+Alt+G is group. These commands don't work. All the buttons work independently, just not combined. Has anyone else experienced this and found a solution?

Thanks

@Matthew_Charlesworth I am afraid this issue was caused by the system incompatibility. Please try use those combination on the right-hand-side of the keyboard to see if that helps fix the issue. If this issue cannot be fixed satisfactorily, you're welcome to contact us via support@anker.com and we'll surely do our best to help:)

Having a similar problem with bringing up an OmniFocus quick entry window, which uses control-option-spacebar. Works fine on my MacBook Pro keyboard, but doesn't work at all on the bluetooth-attached A7721 keyboard.

What is "the system incompatibility" referenced above? Sounds like something noted previously, but I don't find any other mention of it.

Hi,
I also have the same problem but don't understand what you mean by "system incompatibility". Does that mean that I should update my mac os x version (I am using Yosemite) . Is there any way to do fix it? the right combo works, but that defeats the purpose of many keyboard shorcuts that assume your right hand is free.
Thanks for any guidance.
