Hey stefan.

I have successfully got my waypoint visibility files to read and write at different sizes.

For starters, when you save the cVisTable, you may need to add an extra byte because when you divide and cast to an int you may lose some floating point info, so you need to Ceiling (round to above integer, but if x.0 then its just x) that value to get the proper size.

When you load you need to estimate the size of the file and get the filesize, if they don't match then you have to re-build the vistable etc. :/ You can get the filesize by using fseek to end of file (SEEK_END ?) and use ftell to get the filesize (in bytes) also fseek back to SEEK_CUR i think.
