- VERSION HISTORY:
-
- V1.2: TreeView problem fixed by Diego Tartara
- Small problem in thumbsize calculation also fixed (thanks Diego!)
-
- V1.1: Added support for Right-left windows
- Changed calling convention of APIs to WINAPI (__stdcall)
- Completely standalone (no need for c-runtime)
-
- V1.0: Apr 2001: Initial Version
