Can I ask exactly which version of the class you were using? I ask because CVS version 1.9 (1.N.5 was 1.6) got a major re-write of the removechild() function. I'd love to hear you say that you did your testing on a version previous to this :o) We've been aware for several months now that removeChild was a very weak function... ---------------------------- Revision : 1.9 Date : 2001/9/30 2:56:32 Author : 'nigelswinson' State : 'Exp' Lines : +144 -80 Description : Major re-write of the removeChild() function. It had developed some fairly major bugs, ie when called it would delete the entire $nodes array. Also fixed some bugs in the _export function ------------------------------ Thanks for your kind comments too :o).
