Distribute Spacing field is disabled if you set a key object BEFORE opening Align panel
Windows 10 Pro (64-bit), Illustrator 24.0.1 (64-bit)
If I wish to align / distribute two or more objects in Illustrator, if I select the objects and click on the 'master object' BEFORE I go to the 'Align' tool window, the distance box remains greyed out as you can see in one of the screenshots below. I find this very annoying, for example, I may have previously been on the 'Transform' tool window sizing my objects, then I copy them a few times and select them all, select a master object then go to the 'Align' window and the distance box is greyed out. I then have to re-select everything and re-select the master object while the 'Align' tool window is open for the distance box to become active. I find this very annoying and Illustrator CS5 didn't used to behave in this way. If this could be looked at please, it would be brilliant, thank you.
Distribute by centers is in the control bar when more than one object is selected, but distribute by spacing is missing.
