Odd problem with tool selection v3.4.9

Using a MacBook Pro with Dimensions 3.4.9

• Ventura OS
• Intel i7 6-core processor
• 32GB RAM

Issue is I selected the Scale tool, arrow with the little box, and there's a white underline to show that's the current selection.  Clicking on the other tools, like the move tool, does nothing.  Tried a long press, tried a mouse, double clicked, long clicked, out of click options and it won't move from the Scale Tool. 

Is there something here that's simple that I've overlooked?  Switching tools is pretty basic function, but I don't seem to have that option.  First time experiencing this issue.
