http://www.zwsoft.com/forum/viewthread.php?tid=2517 We have 2010 version and can't insert ole object, for example the PDF coming in not nice resolution, excel file sometime take the file with some cells missed or some time make it only an empty box, this is one thing the other is if you insert an image and try to use dwf out command you will lose your image resolution, last not least the undo command ( u ) or ( ctrl + z ) is not making undo till the file open status, for example it will do like 5 time undo only and I can't go back to some drawings I erased before 6 times. hanymen5808 2012-11-19 03:09:09 http://www.zwsoft.com/forum/viewthread.php?tid=2517&pid=16299 Hello sir, what is your version number?
