#14 fixed Support survey dates before 1970 Olly Betts Graham

It would be useful if Survex could be made to register dates earlier than 1970. At least as far back as 1940 would be good for me.

#20 fixed Aven crashes on opening file on Ubuntu 11.04 Olly Betts Mike

Opening a 3d file results in the following:-

The program 'aven' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
  (Details: serial 33805 error_code 9 request_code 137 minor_code 8)

Help About... shows:-

Linux 2.6.38-11-generic i686
wxWidgets 2.8.11 (GTK+ >= 2.6)
Display Depth: 24 bpp (colour)
No OpenGL information available yet - try opening a file.

Graphics card is Radeon X1300/X1550 Series

Failure seems to leave the following message in Xorg.0.log:

#26 fixed Aven says "Bug in Program" on certain 3d files Olly Betts Mike

Windows version of Aven 1.2.1 flags "Assertion Failed! ... file line 2233 Expression z<=z_ext" on certain .3d files. Pressing "Ignore" button, aven continue and produces a result but I haven't checked if it's correct! "Abort" goes to "Bug in program detected. Please report this to the authors".

On Ubuntu, the same 3d file also fails. There is no assertion failiure dialog box and it goes straight to the "Bug in program..." dialog.

Graham Mullan referred to the Asertion Failure on the Survex list but doesn't seem to have raised a ticket. I have not seen the problem on any of my "real" survey files but found it with the file cave.3d buried in the Therion samples/survex directory. I have reduced this to a single simple file, attached, which reproduces the problem. It's hard to say how serious this is.
