When I double click a DWG file in windows explorer, most of the time, a new instance of QCAD starts. I would rather have the file opened as a new tab in an already running instance of QCAD, or, if the file is already open, have it focussed. This is on windows 7, RC5.
Curiously, this behaviour is inconsistent, sometimes windows behaves as I want it to. But I cannot make out a pattern, that drives behaviour. Anybody else notice that? Can you help me manage this?
