If I comment this out but include the other 3-4 items, the floats reappear.  And if then I again uncomment the single item (leaving the others uncommented)  the floats disappear again.

These have never caused problems until just now.  I was tinkering with some text several pages before these floats when I started getting the error message "Floats lost".  I tried to track down what was causing this problem, and ultimately commented out the whole section of text (which has no direct connection to the floats in question--they are in a different section  ) which resulted in still getting the error message, but the floats which get lost seem to vary with what I comment out in the text.  (That is, some lost ones reappear, but others disappear) I have no idea how to proceed from here, since anything that might have been embedded in the text I was tinkering with has been commented out, and before I started tinkering there was no error message.

I found one of these commented out in my present version and restored it--again changing which floats get lost, but not the fact that some are always being lost.

Howdy,

Now it's beginning to sound like a list environment of some sort that isn't being closed; i.e., no \end{...}.

Good Luck,
