First contribution comes from Tony T. He reported a drawing which produces
failure consistently: "Basic Electronics.dwg"(in your sample\designcenter
folder). It would appear that color depth is not the culprit at all (at
least in this case). When I debugged the error, I found that the length of
the string retrieved was zero: there is no preview data on these blocks. Can
anyone confirm this?
BTW, that does point up somethng I failed to mention: my limited testing
shows that only blocks defined in a drawing with BMAKE (not -BLOCK or
INSERT) will have preview data. Can anyone confirm this as well?
