What is a boat
.xml? A polar diagram perhaps?
If it is a file that contains some data that the computer reads and interprets (like a polar data) at times it is wrong formatting AT SAVE.
So imagine the file is a polar diagram data and the software
works fine till you edit the .xml. If so, I have seen the following problems this far:
a) wrong formatting at save (editor problem, change your xml editor),
b) wrong data formatting type (a comma in place of a dot, etc.),
c) wrong permissions at save, (in Windows right click, properties, permissions)
d) wrong file type at save (e.g. the editor falling back on its default file type).
It is very often something very silly that you can eliminate by trial and error. Try to find what kind of modification makes the crash. Make one small mod at a time only.
A very simple way to check quickly if it is a file / editor challenge is:
a) make externally (no editor used, simple copy/paste does this in Windows) a copy of the original file. Rename the source file to *_old.
b) rename the copy file to the original source file name,
c) open and edit this file, save. Then open AGAIN, re-edit back to original value, save. Now open this file in the program. The file is the same, except for editor manipulation.
In the above, if you get a crash. Change the editor.
It is very difficult to go wrong if you use the Notepad. Easier with the Wordpad or Word.
