So how many flags are there? Fusion's dialog says that there are just 32:
...but this is misleading. There are 32 that you can name, but after 32 you can still use them - you just can't name them. They seem to work fine, and Fusion even has a different name for them: "internal flags".
It seems that there are 255 of them in total: "Flag 0" to "internal flag 254". Any flag after that seems to just affect flag 254 (eg. you can set "internal flag 99999" if you want, but it'll actually just set flag 254).
Is this all correct? And are these internal flags fine to use (apart from not being able to name them)?
