Cryptext x64 0.11w fix1 - targeted test
=========================================

1. Open Info/About. The current file icon must be visible at upper left.
2. The OK button must use the same flat style as the main-window buttons.
3. Click the About icon repeatedly: key -> AES v2 -> AES v3 -> key.
4. Reopen About: the selected icon must persist.
5. Explorer .$#! icon should follow the selected variant after shell refresh.
6. Trigger a wrong-password/authentication error. The heading must no longer
   contain the obsolete "Entschlüsselungstest 0.10a" text.
7. Re-test one modern CT64FILE-v1 file and one confirmed Cryptext-3.4 legacy file.

No FASM build was performed in the assistant environment.
