RE: The problem is that that is exactly what FIND is doing. Note that is is inconsistent... as I recall, the only filter that has been problematic is the account filter- none of the other ones, such as Name or Number or Transaction Type have ever stayed populated. 

Don't know, then. I've not been able to reproduce it and haven't seen it reported before. When it happens, is any other window open? It so, Find may be cleaning the account from that window.
