Yes Glenn, you hit the nail on the head. This is the "fun" bit Rob and I ran into when adding the balloon tips to the NotifyIcon. I've been working on the specifics on how to *fidget* the methodology appropriately into the code for Win32-GUI, and have about half of it done. Not that does me any good at the moment as I have to use Win32-API to pack/unpack the differential structures....XS is prettier.
I was simply looking for other examples where this occurs. NotifyIcon thankfully actually has a structure that simply had data fields added to the end, and only the end, thus leaving one capable of simply setting the SizeOf to the previous versions size! Not every object has been so nicely ported between windows versions. Win32::GetOSVersion doesn't solve all the problems btw, but thanks for note on it for others that may not have seen the function before :) [started with that].

I haven't yet had a chance to look at his code changes. Everything is possible, of course, but it seems that the MS way of doing multiple versions is to define different length structures, whose length is initialized before passing to the API, and the "easy" method of doing that is recompiling with newer header files, rather than dynamically determining which version to use based on the OS version. So, MS doesn't make it easy to build a module that customizes itself to the capabilities of the OS... but then again, their design center is to make things easy to encourage people to upgrade the OS.... want this feature? Upgrade the OS. And if an App wants to use a feature not in Win95, and does so using the MS way, then it locks itself out of the Win95 market... want this app? Upgrade the OS... etc. Upgrade, upgrade, upgrade, more $ for MS :) But, it is possible, you just have to work harder at it.
