Works fine for completely new survex file.

For an edited, pre-existing survex file,

deleting all the survex blocks means that some other pages just crash, e.g.

I am having great trouble getting the 'parent' block to work correctly.

It gets overwritten, and then nullified, on repeated SAVE & import.

I should learn how to step through with the debugger.
