Layers in eDrawings 2008

We've been taking a look at using eDrawings as an AutoCAD DWGviewer.

One problem we've come across is that any layer in a DWG that wassaved as frozen isn't visible in the eDrawing viewer. Checking orunchecking the checkbox in the displayed layer field has no effect.

Layers that are turned off can be toggled on and off though. Isthere a work-around for this? Changing 20 years of CAD files isn'tmy first choice of things I'd like to do.SolidworksEdrawings
