After upgrading to Build 214, the + and - keys on the number pad are disabled when trying to enter values on a Volume Envelope. All other keys on the number pad work properly. The keys work properly in all other apps, and they worked properly before B214.
Those keys are used for preview zoom in build 214.
So it's FEATURE? They couldn't have used Ctrl, Alt, or Shift to assign that function? I wouldn't expect keys in their default state to EVER be changed. Shortsighted at best. Can that behavior be disabled?
In theory, the preview window is inactive when the track envelope is active, then the number keys should work on the track envelope instead of the preview window. But that's clearly not the case.
You're correct. If I right-click on an envelope point, then click Set to, I cannot enter a negative number unless I use the - from the top row of the keyboard. The same goes for the + symbol, but Vegas assumes if it's not a negative the value should be positive. It would be good if there was a way to disable this behavior and return to the previous behavior. Maybe in a future update, but I've been requesting larger envelope points for 4K monitors for more than a year, but that hasn't happened. Disabling the new behavior for the + and - keys sounds like an easier fix, though.
Seems to be a focus issue, will be fixed.
