Export to .ico not working correctly

And also notice the advisory message in the export dialog informing you that icons AND compression are not supported in all image viewers. That might be explaining the different results you are finding with different viewers.

You can uncheck the Compressed (PNG) check box (other red arrow) and then the advisory (as well as compression) will go away.

Lastly, I've always preferred the Greenfish Icon Editor program for editing windows icons.  I don't know if that will suit your purpose, but if you are unfamiliar with it, you should look into it, just to have options. 

Cool ---
Thanks for the info!
So - Funny thing --- the way the GUI is designed - I never would have clicked on that "Select File Type (By Extension)" item - As it had a box there, and appeared to be already "checked" (with a weird white plus-sign - which I've never seen used in Windows - ever.). In fact, I was mystified as to what that control even meant!  It is very unclear as to whether something has been picked already or not, and also unclear that clicking on it would do anything.  Oh well --- that is why I never found that list.
On that other item -I did see that warning - and I have no idea what the actual ramifications of that will be or could be. It could indeed be the reason for the odd behavior I saw.  I have a little suspicion that it is driven by the fact that numerous layers are in there, and there's just no control over which ones get 'chosen' to view.  (I will say that even after exporting to a .tiff and then using it to create the .ico file has still resulted in different things being presented at different View As XL, L, M, or S settings for the Windows Explorer.  My expectation is that to control that, I'll need to have a .tiff that has the different sizes explicitly in there? Just guessing.)
I will look into Greenfish since I am particularly focused on icons at the moment.
Thanks again!
