[RASMB] Error in interference scan acquisition

[Kristian Schilling]

Dear Jeff,

thanks for your input and for taking the trouble to search for the exact 
location. I find this explanation highly probable, and it could also 
explain why the bc<some number I forgot>rtl.dll crashed when we later tried 
to launch the xli software. As a box came up that explicitely stated a 
loating point divide by zero. Apparently the dll was attempting some 
calculation with corrupted initialization values and was not defaulted to 
some reasonable action for the case of a zero in the wrong place...

However, as the service technicians (in the meantime, their number has 
increased to two) have bulldozed the windows installation and are 
reinstalling the complete system (right now they are caught with driver 
problems that may occur when we try to install an eight year old operating 
system on an eight year old PC...), we can't check the xla.ini file any 
more. Now this would have been really interesting...

Thanks again,
Kristian
