Hi.
Thanks for providing us the template file with details.
Well, I have tried and implemented your scenario and performed all your steps using your template file with v2.0.1.2008 version of the GridWeb, but could not re-produce any issue at all. I have conducted the test 2, 3 times, inserting different sets of values in "fixture_list" cells including A4 and checking other sheet (including "PCA_BFT") cells including A22. Everything works fine as expected. Which IE browser type you are using, I am testing it on IE6.0 though.
Anyways, we will further check it if we can find any issue on our side.
Thank you.
