_______________________________________________________________________________________ Note: This e-mail is subject to the disclaimer contained at the bottom of this message. _______________________________________________________________________________________ Definitely agree on splitting out Memo fields. Also try pulling data into the form using a "Just in Time" approach. Be careful when using bound tab forms as the user may only use one of the tabs (out of dozens), but all the data is still being pulled into those other unused, unseen or hidden tabs. "Unbound seems like it will be the ultimate answer". Yep, the deeper I get into this Access Database business the more and more I find I make the forms unbound and only when the user is ready to save the record (by pressing a save button) do I write the data back into the source table using a recordset. It takes a bit more work in the code to setup, but the gains in stability, speed and reliability are well worth it IMHO. I know there have been some, ummm, interesting discussions on here about bound vs unbound but I am finding unbound is the way to go.

I'm giving them a range of suggestions - the form they're getting the problem with is based on a needlessly complicated query, for a start, and is retrieving an entire 500,000-row dataset then filtering it to edit 1 record. Ugh. Ugh ugh. Unbound seems like it will be the ultimate answer.

Either ODBC or ADO-OLE should be used in these cases or corruption will persist. The BE data may be corrupted to the point where a restore from backup may become a regular event.

We're talking Access 2003 on Citrix, FE/BE split, 16 users using 2 .mde FE's to access. The error is fixed by everyone exiting the database, the BE is compacted and repaired and the offending record deleted. The PK on the main table is often lost at the same time and has to be recreated, along with any relationships. A little googling suggests that the error is caused by corruption of the record, which may in turn be caused by dropouts in connectivity (that's not clear but as 'disk or network error' is also commonplace, I suspect it). The table contains 2 memo fields, and some people have reported that these are particularly problematic viz. this issue. Apart from unbinding the form and controlling the save process in code, can anything be done to ameliorate this?
