Active X Error on Subform

[Tezdread]

Hi all,

I have a form with two sub forms and when I enter data into one of my subforms I get this error?

A Problem occurred while Microsoft Access was communicating with the OLE server or ActiveX Control.

Close the OLE server and restart it outside of Microsoft Access. Then try the original operation again in Microsoft Access.

I've checked the relationship and linked child / master fields and it looks ok. Does anyone know what could be causing this?

I am getting this error on a couple of different PC's running WinNT4 and Win2000.

Shutting down doesn't help and I don't get this with other databases. When I open the form (subform2) on its own I can enter data, just not when it's part of the main form?

ah, shutting down does seem to help...but why am I getting this error?
