You see several small yellow boxes containing exclamation marks (!) throughout your CAD interface, as shown below.
This issue is the result of a system variable known as ANNOMONITOR being set incorrectly.
Set the ANNOMONITOR system variable to 0:
Type AnnoMonitor in the Command line. When prompted to set a value, type 0 (that is, zero – not the letter O). Press Enter.
The boxes should disappear from view.
