locking problem

One of my clients is having an intermittent problem with the program "locking up".

User go in a sit on a record.  They have the ability to add memo to this record which is in a separate memo file.  The popup screen to add these memos is had dummy fields and when finished is posted to a free record in the memo file.

At the point of saving the memo, the system locks up and no one can add memos to the memo file.

The solution that works is to have everyone exit out by clicking on the window pane <X>.  Then I go in an rebuild the 4 automatic indexes.

There are currently 1,647,931 records in the memo file.

Each index is built on multiple fields.

One other thing, when the primary record is displayed, the lower half of the screen is displaying up to 8 memos depending whether they are 1 line or 2 line memos.  This is read in from automatic processing into dummy fields.

Any suggestions as to what may be causing this problem.
