Hi everybody,

Ok, today is probably not my best day :( Each time I invoke my application and check CheckBox Resolve Dupes, VFP crashes. It's on one particular table only. This table is a part of DBC and has lots of field rules.
In CheckBox.Valid method I have this code:

* 3/15/99: support enablement/disablement side-effects on toggling of Resolve Dupes mode
* 3/23/99: resolve mode should implicitly filter to non-blank dedupeflag if there is no current filter.
*     Invoke new navUpdate instead of making direct calls to bare navrefresh.
* 3/31/99: give user an easy way to exit from Combine mode by exiting from Resolve mode.
set step on
* implicitly filter to non-blank dedupeflag if there is no current filter
if this.value and empty(filter())               && switching into Resolve mode
     set filter to dedupeflag # DDFC_NONE     && restrict to possible or resolved dupes
     thisform.FilterStr=filter()
     locate
endif

* clear Combine mode if currently in effect, as an easy way to cancel from Combine action
thisform.deducombmode = .f.                         && turn off mode of selecting records for Combine

thisform.navstand.navupdate()               && force adjustment of enablement/disablement states
*thisform.grdBldMstr.Refresh()
*thisform.grdBldMstr.SetFocus()
*thisform.Refresh()

I added locate today and now it gives me an Error on this string. Otherwise it gives me this Error in Navstand.Buttons.Freshen on SKIP line.

I will check, if the problem with this particular table or it's a more general problem. In any case, I'd like to know, how to prevent this Fatal Error, if it's possible.

Thanks in advance.
