[OpenLayers-Users] WMSGetFeatureInfo + xy mouse coordinates, can this be done?

[Alexandre Dube]

50~ shouldn't be a problem.  IMHO, it would be a good idea to make the

Alexandre

Besides possibly changing my features into markers from my WFS and giving those markers tooltips/hotspots but not sure what the performance would be on that since I need sometimes 50+ markers.
