Hi Paul, yes, I experience the same problems with NS6 as before, when trying http://www.abelian.demon.co.uk/tssp/geotc/geotc-test.html after running online about 20 minutes, I got the results at the end of this email. I had to quit the warning message 4 times, and aborted the run afterwards. I don't see how it should have changed, since Bart's discoveries of .... "...identified a problem in J_Run.js. (compare_Cresult is undefined). Well, it took a few seconds to see why. The output functions were "nested" (doh!). Anyway, popped them out of main run function and popped them back in just below it. Ran NS7 without errors. It's not as quick as IE6, but it runs ok." I also tried the content of FanTC_x7b.zip off line with both of IE6 and NS6: Fine with IE6 (only ignoring the warning) but yet the same as before with NS6. Bert must have set something different in NS7, in order to get his much better times of execution.
