 I've been using QGIS lately on a Windows platform, Server 2008 converted
 to workstation mode (basically Windows Vista -- same kernel).  Running
 64bit OS, 8GB of RAM, ATI Video card, etc.  It seems QGIS isn't as stable
 on Windows as I hear it is on Linux, however, I can't vouch for this as I
 don't have a Linux system with X installed (just commandline).

 Anyways, the problem seems to mostly manifest itself when I am selecting
 roads by hand using the selection/lasso tool, using GIS data from the
 Tigerline website
 (http://arcdata.esri.com/data/tiger2000/tiger_download.cfm), specifically
 in Maryland counties.  I typically download four layers per-county: Roads,
 County 2000, Designated Places 2000, and Water polygons.  They are layered
 top-to-bottom as Water, Borders (County 2000 with no fill, just outline),
 Designated Places, and County (County 2000 again, no outline, only fill).
 I import the roads as-needed for some maps I'm drawing for a project,
 depending on which county I'm working in.

 I also have surrounding counties from PA, VA, DE, and WV imported in with
 similar layers.

 I've seen this particular annoyance on QGIS 1.0 and now 1.1, so it seems
 to be a fundamental flaw in the Windows releases so far.  In 1.0, the bug
 manifested itself as a graphical "break", kind of like a mirror shattering
 effect.  Sometimes the program would crash, and other times, it just got
 all weird, forcing me to process kill it from the task manager.  In QGIS
 1.1, the program immediately crashes.  Improvement?, I suppose.

 Ideally, on Windows, this type of crash should be very infrequent, but
 it's happened to me 3-4 times today already, which is actually more times
 than in QGIS 1.0 on average.

 It's hard to give anymore concrete information, as I've only been working
 with this program for about two weeks now, and I'm not fully versed in all
 of its capabilities, and in GIS software in particular.  But if there's
 any kind of logging I can enable to provide some measure of debugging, let
 me know, and I will see what I can do.
