I have been building a worksheet for weeks now. I opened my document today and only 5 of my 27 pages remain. What does remain has to have the "F9" button pressed to calculate. It doesn't normally require that. It opens with everything calculated typically. I was able to open a previous version of the document that was from 4 days ago, but I have lost 2 pages of calculations unless I am able to recover the lost pages somehow. I saved the document and it shows to have saved yesterday right before I shut my computer down for the night. Has anyone ever had this problem before? Is there a solution?

I have never heard of this before.

Can you post the worksheet?

An update to this...I just got off of the phone with a PTC representative and he says that without being able to recreate the issue on command that there is really nothing at all that he can do. This very same issue has happened twice to me now and both times it deleted back to the very same spot. He didn't seem to think that it was possible for the problem to be within MathCad. He suggests that Windows is the one deleting the contents of my file and changing the "Auto Calculate" feature to be checked off when that feature is always on by default on my worksheets that I create.

Mike,

Please keep in mind that the file was a 27-28 page document yesterday and that the auto-calculate feature was turned on when I saved. The file size is 1/3 of the size that it was before too now. The file was saved on my hard drive and not a server. I was able to recover a version of the file that was 4 days old due to the computer doing an auto-backup when it installed a Windows update on Monday.
