I'm encountering a strange issue when I select a clip and go to the inspector to change the crop. When I click on one of the parameters and then then use the up or down arrow keys to make an adjustment, often it will change by 6.7px at a time instead of 1.0px. I have to use the drop-down menu at the top right of the crop section and select "Reset Parameter" to get it to go back to changing by 1.0px. How can I force these settings to ALWAYS and ONLY change by 1.0px at at time when using the arrow keys for fine adjustments?
