Delphi XE2 Update 4 Hotfix 1 and Help Update 6 for XE2.
If I am in the IDE, highlight an object name such as TLabel, then hit F1, I am transported to the description of Vcl.StdCtrls.TLabel in Delphi's help application. The page gives me information for both the Delphi and C++, but I can click on Display Preferences in the top right and 'un-tick' C++ so only the Delphi information is displayed. But now, if I click on TEdit (either by clicking within the help page under See Also or by selecting and F1-ing in the IDE), the Display Preferences automagically reverts to both Delphi and C++ when the TEdit Help is displayed.
If, on the other hand, I go directly to embarcadero online help, for example: http://docwiki.embarcadero.com/Libraries/XE2/en/Vcl.StdCtrls.TLabel to get the same information (using Chrome), the browser (?) remembers my Display Preferences and, once I have un-clicked C++, will only show me the Delphi information if I click on TEdit or further pages.
This drives me to distraction, as I am not the least interested in C++. Have I missed some option within XE2 to only select Delphi in Help's Display Preferences, or is this a 'feature'.
