Overlay issues with Openlayers

[Hamman Samuel]

I've been trying to get an overlay map showing, like the France map in the Placemarks Working Example: http://timemap.googlecode.com/svn/tags/2.0.1/examples/placemarks.html

However, I'm using Openlayers and for some reason unknown to me, I can't get it to work. I switched to Google Maps v3 (used in the example too) and it shows well. But I prefer to use Openlayers if I can. 

Related to this, I have successfully added a polyline and polygon to my map with Openlayers, but this causes a new issue! No other place-marker can be clicked anymore on the map, and any click just shows up the bubble related to the polyline or polygon.

I can provide my code and working map if needed, but since I haven't seen much documentation or questions about overlays and polys with Openlayers, it would be great if anyone could help clarify the basics first, thanks

I think that some of your polyline issues may be covered in the topic 'Path is completed when clicked upon'.
