Hi Andreas, Thank you for your reply.
The version I use is TOOE680_m6 and OS is windows xp sp2. You mean that when do "undo" operation, the temporary elements are all in BigPtrArray? After some tests, I found that other web pages don't have this problem except www.sina.com . Although the contents of the page change every day, this problem exists in this version all the time. If you can find this version and reproduce this bug, hope you can give me some help. Thank you very much. Best regards lijian 2007-03-01
