Windows 95 - does anyone still use that?:) For my Win32-GUI project I use 
functionality that limits my users to Win 2000+ (which in my case isn't a 
problem). I would have thought win 98 should be the minimum supported 
platform?

When you say compiled PPM what do you mean? Would a PPM built by Win98 be 
different from one built by XP?

As for new functionality, I'm sure there are features in Win32-GUI now that 
would only work on 2000/XP (such as various options for dialog's) so why 
would NotifyIcon's balloon tip support be any different?
