This is seemingly related to the touchpad's 'touchguard' function, but applied to the pointstick.
On my Dell E5550 (late 2014), there is both a touchpad and a pointstick, each with their set of buttons for left and right clicking.
When using the pointstick, pressing a key on the keyboard disables any input from the touchstick or its buttons for 1 full second. This is to avoid moving the curson or clicking by inadvertance whyle typing.
In Dell's Touchpad properties, the place where pointstick parameters are also found, the touchpad section includes a setting to enable/disable 'touchguard' as well as setting the amount of time for the inhibition of the touchpad's surface and buttons.
It works as intended, because keys like Ctrl, Alt and Shift don't inhibit touchpad input, allowing for Ctrl+click or Shift+drag combinations.
This doesn't work for the pointstick.
First, there is no way to disable touchguard for the pointstick. Second, as it is always enabled, meaning typing inhibits the pointstick and buttons, it doesn't differentiate between keys, meaning Ctrl+clicking requires the user to hold the Ctrl key for at least one second before pressing the left click button!
The one second delay is fixed, and cannot be adjusted, like is the case for the touchpad.
As you can imagine, it is incredibly annoying.
Would you please provide me with a solution?
Thank you.
