Vista / Windows 2008 Server support (fixed a bug causing the component to crash on those OSes)
Added a separate version of the BotDetect ASP component setup for 64-bit (x64) machines
Added a CAPTCHA Reload button (allowing users to request a new CAPTCHA code if the current one is unreadable) to all of the sample ASP projects; removed the BotDetect Refresh Demo ASP sample project (since it is superseded by the Reload button functionality)
Added Ajax CAPTCHA validation support to the LanapBotDetectHandler.asp file, and a new ASP sample project demonstrating Ajax CAPTCHA validation (CAPTCHA Ajax Validation Sample)
LanapBotDetectHandler.asp general refactoring & cleanup: added support for multiple CAPTCHAs in the same ASP application, better variable names, more comments, better invalid request processing
Fixed a bug in the CAPTCHA randomization ASP sample, where reloading the CAPTCHA image without reloading the whole page bypasses the randomization
Changed CAPTCHA validation code in all ASP sample projects (to directly compare the user input to the Session state value), while keeping backwards compatibility with older code (comparing the code hashed values)
General refactoring & cleanup of all ASP sample CAPTCHA projects: improved usability by automatically lowercasing the CAPTCHA code input while typing, XHTML Transitional compliant code, CAPTCHA layout definitions moved to a separate CSS stylesheet, fixed some field name inconsistencies; moved all ASP sample CAPTCHA project to separate subfolders in the installation folder
Installation cleanup: removed the Component folder from the setup, all binaries are now kept exclusively in the Redistribute folder; the gdiplus.dll redistributable is now only installed for Windows 2000 users; replaced the outdated offline help with a link to the online documentation
