Strang problem with Delphi 12 IDE

[Jud 1]

I'm having a strange problem in the Delphi 12 IDE on a Windows 11 desktop.  First I downloaded the trial version of Enterprise and entered my license number.  (My license is for the professional edition.) There were strange problems in the IDE.  When searching, if I searched for "xyz[" or "xyz(", it would give an error message about mismatched [ or (, and not search.  If I search for ".xyz", it ignores the period.  There are other things, like much of refactor is disabled.  Sometimes "find declaration" doesn't work.

 

I uninstalled Delphi 12 and reinstalled it from the iso file.  I had the same problems.

 

Then about 3 weeks ago I installed it on my Windows 11 laptop to take on a trip.  It DOES NOT have the problems!

 

What could cause this and how can it be fixed?

AFAIK, that is simply not meant to work in the first place.

You are searching with the "regular expressions" check box enabled, hence the message

Just got back - that might have goofed something up.

That was the problem!  It must have gotten checked by accident.
