Long file names when inserting blocks

Just a small bug.I noticed in an earlier version 4.0.0039 that when inserting blocks with a filename such as blockname.200.dwg the insert would fail.4.0.0041 has the same behaviour. Although you can open the file you cannot insert it as a block. Obviusly the file truncates at the first period.Not a major problem, but something to note for the future.RegardsKim
