or rectangle
tools. When I try to drag them across the drawing, nothing appears until I release the mouse button, at which point I get a selection box with the usual tool handles (both for the box and specific to the object) but no object appears.The usual methods for editing an object's appearance work as usual, as in: I can paste a style or make changes to the line or fill properties, but no changes actually appear in the selected object (ie: it remains invisible) and as soon as it is de-selected or another object is selected, it disappears leaving no trace it was ever there (which, I suppose, it wasn't).
Normally I'd suspect bad defaults, but I can't find anything that corrects the problem, and the fact that I can't paste a new style onto the object makes me conclude I'm either unaware of what might need correcting, or there's a bug.
I'd appreciate any suggestions.
