TwwDbGrid.SelectedList.Count not working

I am using D5 with InfoPower's TwwDbGrid.  I have enabled the multi-select option but whenever I try to access the SelectedList.Count property, no matter how many records I have selected, the value returned toggles back and forth between 0 and 1.  Any ideas what might be causing this?

I use TwwDBGrid and this seems to work fine for me.
At what stage are you reading the SelectedList.Count ?
Maybe post your code to make it easier to find your problem.

I've tried OnMultiSelectRecord, OnMouseUp, and OnKeyUp.  

I'm using an ADO connection and I noticed that the cursor type was a forward only cursor and thought that was the culprit somehow.  But even after changing that, it didn't help.

Perhaps the problem is that I'm using my own "home grown" table object (someone else wrote it for me - so I don't know everything that's under the hood).  Maybe I should try using a TAdoTable.

Yes, try different table object.
The selectedlist is a list of TBookmarks, so your data/table would have to support bookmarks.
Sorry for delay, I think we have a big time zone difference!!

RickJ,

I believe you hit it.  I suspect that bookmarks are the culprit.  TDbGrid / TTable, as well as TwwDbGrid/TwwTable work just fine.  Thanks!
