This has been a difficult bug to reproduce, but it happens with enough regularity that it is extremely frustrating when it happens.

Sometimes, when I add, rearrange, or remove an input from my setup, a shortcut key input will change. For example, let's say i have 3 inputs all set up: Input A, Input B, and Input C. If I have the "F1" button set to Fade in Input A in 500ms, sometimes if I add a new Input D, or delete Input B, or move Input B to be after Input C, then the F1 shortcut will change itself to use Input C for no apparent reason. I have seen this happen in cases where the order of both inputs has not changed at all, and times where it affects one shortcut that uses Input A but not another. It's infuriating to have you shortcuts changed out from under you. I had several gaffs in my broadcast tonight when I used a delay to save a clip, and when the clip added itself to my input list, one of my shortcuts changed input, and I would hit that shortcut to switch inputs and it would throw up something entirely different.

It has been a bug that is extremely difficult to predictably reproduce, but it seems to happen with enough regularity that I feel like I have to check my shortcuts every time an input changes to make sure they are OK.

Hi,

I haven't seen this issue in testing (have you tried the latest vMix 9 release?)
I would suggest trying different combinations of actions until you can consistently re-create the issue.

It's important to point out that when you select an input to assign to a shortcut, that "link" is only valid for as long as that input remains open.
Removing the input will disconnect the link to the shortcut, even if you add it again later.
