Yes, you can do that as well - placing the modified .pas file in your
LIB directory. However, when you then compile your .pas file, it will
replace the orginal .dcu file. That's why I always place modified VCL
source code units in my project directories only (for each individual
project), so the .dcu files will not overwrite the original ones (until
the patch from CodeGear appears).

The Windows unit is automatically calling the W-versions of the Windows
API, and passing String and PChar, which are now UnicodeString and
PWideChar, so that's not something to worry about. Unless you explicitly
want to call a Windows API function by adding the W- or A- postfix
yourself...

Thanks for the kind words. I must admit that the above sentence about
the global globalisation wasn't written with any pun intended at the
time ;-)
