Well I didn't have nutthin but problems with the 1.07.6 beta and went back to 1.07.5 and been playing all day and not a crash or a popup error box or anything. Something buggy about 1.07.6 for me and it's no big deal there's not enough in 1.07.6 to matter to me as long as I can play without crashes and error messages.
This might sound silly, since I'm actually really bad with computers (and can only state what I think I know):
I had a problem with DW giving me CONSTANT "Undefined Exception" errors at seemingly random and increasingly problematic points. The problem was this:
tm.asp?m=2973379
Distant Worlds was originally a garage project, and despite the generally slick interface (IMO) it uses some very unusual methods for storing and retrieving data. Methods that are easily disrupted by Windows 7, it seems. By running DW as an Administrator, and making sure that nothing funky is going on in your C/Users/<user name>/ect... folder-tree you may be able to solve your problems.
The only reason I bring this up is that you seem to have experienced some rather unusual and unique problems with the last patch, and this is the biggest computer-related issue i've come across with DW.
