"Finished" early: Raith150 program crashed

[James Conway]

Hello ALL:

We have seen this problem from time to time on the RAITH computer when 
running the RAITH150.exe application.  Often after cancelling a exposure 
or when doing a lot of changes in the editor without saving yur changes 
regularly.

  While I am not sure, I think this is due to some memory addressing 
issues whereas the WINDOW XP OS doesn't allow an application to address 
specific addresses in the memory arrays if it has not been allocated 
within the application. I am not a windows software person so maybe 
someone else has a better diagnosis or opinion.

If this occurs on the system it is recommended to gracefully *shut down* 
the RAITH computer and restart the WIN XP OS. and then the RAITH 
application.

I will bring this up at the RAITH Users meeting at Three Beams in late 
May to determine if other users are encountering this issue and how it 
can be reduced or eliminated.

Yours,

James Conway
