Thomas,

I will check this out using your guidelines. Will get back to all of you and the rest. Thanks.

Weird though, how come it works if it's a few thousand recs, but freezes up on its current levels (90,000)? Client reported that the time it takes to load the concerned forms increases as they went on, from minutes to HOURS(!), till the other day, when it really freezed up.
