3.0.8
Setting:
Application Preferences - Widgets - Command line - Show information as dialog: Ticked!

If I use the Info Tool Polygonal Area and decide to close it with a right mouse click the "Show information" dialog window pops up - just as expected.
If I close the Dialog window with the OK Button .... a "CAD Tools" Menu pops up. Not expected ;-)

By the way - any chance to control the number of digits after the decimal point in the Info dialog window? 15 decimal places are most of the time just to much!
