-Began looking at bugs reported since the release:
-The menu background colour issue appears to be a known Windows bug, documented here:
http://www.tsilang.com/delphiglobalizationtool_faq.html#20
There may be a workaround we can use, also explained on the page.
-The Chinese interface issue appears to be something much more general, afflicting all TntUnicodeControls; they no longer seem to support widestring captions! Created a sample project demonstrating the problem, posted it, and then explained the issue on the Tnt Webboard and on the relevant Borland newsgroup. Hope this gets fixed soon, assuming it's not something stupid I'm forgetting about. But it does look as though the code worked fine until I installed the October release of Tnt components, and then it broke.
-Looked at the display of disabled images in menu items, and found there's no good way to avoid Delphi's auto-creation of a crappy disabled image (often just a grey box).
