Hi. I have been having problems with lineweights for ages but I had a work around, now that has stopped working.
I have been using the same ctb file for years - many years - and it always worked perfectly. However suddenly all normal lines have started plotting really thin and feint - polylines are OK.
I have tried changing the default lineweight to really thick, but nothing changes - is there a default somewhere that overrides the "lwdefault"?
