Focus Marker Problem DwgPreview SlideView

Bricscad 11.4.6
OpenDCL  6.0.2.5
Win XP

I am working on a 'dwg browser' that can display DwgPreviews and SlideViews. I notice a problem with the dotted line ('focus marker') that appears in the preview or slide that has the focus.

1.
First display of dialog: Focus marker is correctly on slide A000.

2
Hit Tab: Focus is on slide A001 but there is no focus marker.

3.
Hit Tab: Focus is on preview A002 and there is a focus marker.

4.
Hit Tab: Focus is on preview A003, but both A002 and A003 have a focus marker.

5.
Hit Tab: Focus is on slide A004 but there is no focus marker on the slide and the focus markers on A002 and A003 are still visible.

6.
Continue hitting Tab: Focus markers on A002 and A003 stay visible until they receive the focus again: then the markers disappears.

7.
After temporarily switching to a different application and coming back to the cad program the focus marker is correct.

Hi, I recommend you to set or remove highlighting rectangle by yourself using

(dcl_SlideView_SetHighlight Color [als Color])
(dcl_SlideView_RemoveHighlight )
(dcl_DWGPreview_SetHighlight Color [als Color])
(dcl_DWGPreview_RemoveHighlight )

Thank you Fred for your answer. Your suggestion makes sense, but a slide with a highlight looks different.
Strange how the highlight rectangle has two different offsets... Perhaps a Bricscad thing?

Try to remove the focus rectangle by focussing another control after OnSetFocus.

There was a bug in the slide view control that caused a focus change to not trigger a repaint. This should now be fixed in the OpenDCL 7 alpha build.

The problem has indeed been solved in OpenDCL 7 alpha. Nice work.
