QuickBooks 2005 Two times in the past week I entered my posted transactions for the previous day and shut down QB. When I opened it up the next day, I found hundreds of blank (but numbered) transactions listed after my last entry all with the same date and ending balance as my last legit entry. I could not figure out why this happened or how to erase all of these "entries" at once. The first time this happened, I had to erase each one individually in order to clear space for my next transactions....very time consuming! Now it has happened again and I need help. Here are the particulars....last transaction that I entered: # 1893 dated 06/04/2008. After this one, #'s 1982 through 2458 all dated 06/04/2008 mysteriously showed up. I can type in new "Checks" but it will not accept any "Deposits", so I'm stuck, since 06/05/2008 starts with several deposits. Any help will be greatly appreciated! Mark O

This sounds very much like a corrupt database. Blank transactions should not be allowed by a datafile that is fully intact.
You can start by verifying the data. Make sure all of the windows are closed, then go to file, utilities, verify.
If the verify passes, (and it may, even if damage is present), you may want to take the step of rebuilding the data.
Personal preference, I like to copy the company file to the desktop and run the rebuild on the copy, that way if everything goes to heck in a hand basket, the original file is still there.
If the issue continues after a rebuild, you may be faced with a situation where only Intuit can attempt to repair the data. The only problem is, they no longer support this version, and will only work on the file if you are upgrading to the 2008 version!
One way to quickly get an indicator the data is damaged, run a standard balance sheet for all dates on a cash basis. If the two bold numbers on the report are not in balance- you can pretty much bet the company file is damaged. Remeber, this type of issue will only be seen in a single company file, other files on the same computer can be fine.
