actually you could.  Can you please re-install Adobe Shockwave Player, verify 
that Hugin crashes properly, and then try different versions of Hugin on that 
same system?

I assume you are currently using Hugin 2011.0.0 from 
https://sourceforge.net/projects/hugin/files/hugin/

Please try 2010.4.0.  If that one crashes as well, go back to earlier 
versions.  At each step, reset the Hugin preferences.

You may want to back up your current preferences, it is all in a Windows 
registry key called Hugin.  Sorry, I have been away from Windows for too long 
to recall the exact key.  Search for Hugin with Regedit and export it.  Maybe 
a Windows user reading this ticket can help you with more specific 
instructions.

After testing in the past, please test in the future as well.  There is a 
2011.2.0-beta1 at the above mentioned location too.

Last but not least, repeat the tests without Shockwave Player.

I am relatively confident that Shockwave Player is not the culprit, but it 
only brings this bug to manifest itself on your specific configuration.

Another variable you could test:  hide the Overview pane in the FPW, restart 
Hugin, and test.  The status of the Overview pane is recorded in the 
preferences for the next startup, and the Overview pane is the major new 
feature introduced between 2010.4 and 2011.0.  Both the FPW and Shockwave make 
use of the video card and might clash on its memory handling which would 
confirm some sort of memory leak.

You might have to uninstall Shockwave Player, hide the Overview, close Hugin, 
reinstall Shockwave Player and test.

This is a lot of tedious work, sorry, but it is very important information to 
collect and can help us identify the exact location in the Hugin codebase and 
its timeline of the change that introduced the bug.

Once we zero in on that change, fixing it becomes easier.

Thanks
Yuv
