One of the columns on a grid is linked to an Integer field RESUSAGE.RES_NUM

I have loaded the possible values for Resource_ID into an array
SELECT NAME,RES_NUM FROM RESOURCES INTO ARRAY ARESOURCE

I wanted to put a combo-box into that column so that it shows the NAME instead of the RES_NUM. So I deleteD the Text-Control that was in that column, added a combo-box and set the Controlsource to RESUSAGE.RES_NUM. That column is 196 pixels wide. I set SPARSE to .F. and the other attributes.

It works perfectly upon loading and shows the information properly and in full width. However, as soon as any first field in that column gets the focus, all fields in that column shrink their contents to approx. 70 pixels wide and abbreviate their contents. It is still working ok, however, it displays only part of the value.

Is this because the Controlsource is a numeric field?

Is there any know fix to this kinda thing?

Thanks so much in advance again!
