problems with lyx on cywin on winxp

[V. Sharma]

I have been using the cygwin port Lyx1.3.2 on WinXP professional for some 
time. The latex distribution is current Miktex. I have noted that often 
while working on a document in Lyx suddenly Latex is fired, my computer 
gets heated up and the fan comes on. Running task manager I can see the cpu 
usage to be 100% and there is latex.exe using most of it (>80%) cpu 
capacity. This is without me invoking it or attempting to write to dvi or 
pdf.I have to kill this process and the fan stops soon and cpu usage 
returns to sensible levels of about 10% Has someone seen a similar 
behaviour? Is there some way to prevent this as I use a notebook and this 
behaviour uses precious battery juice. any help appreciated vivek
