constrain with shift key not working
I'm trying to move the bottom line of a text box.
I select the box's line with open arrow, hold down the SHIFT key to constrain - and it automatically deselects the type box that I was trying to move. I can select the line with the open arrow and move it that way, but it's too easy to make an error and shift the box. I need the corners to remain perfectly square which is why I'm holding the shift key.
I've had this problem with the last few upgrades.
I'm an Adobe Illustrator user for more than 25 years - certainly not a newbie.
I'm having this issue, shift not constraining and also not able to use shift for multiple select.
