Survex 0.99-prerelease7

[Amoebatron@aol.com]

A handful of things I noticed about the version of Aven that comes with this prerelease (on Win200):

[1] Opening a .3d file by double clicking or right clicking and selecting 'open' causes Aven to launch.  The survey tree is correctly populated with survey and station names, but no survey appears.  Moving the cursor over station names in the tree causes a highlight to appear in the centre of the panel where the survey ought to be.  If Aven is launched and then a .3d file is opened by using the 'File' -> 'Open...' menu item, the survey is displayed as expected.

[2] When the cave is rotating, if the cursor is moved over the panel containing the survey, rotation falters.  I wonder if this might be related to the fact that during rotation Aven is still trying to calculate inter-station distances - I don't think it makes much sense for this feature to be enabled during rotation, anyway.

[3] Keyboard shortcuts; there seem to be some problems:

Tilt to higher viewpoint: Can't find anything that works
Tilt to lower viewpoint: Can't find anything that works
Zoom in: Can't find anything that works
Zoom out: Can't find anything that works
