[TxMt] latex typesetting command runs for very long time

[Dan Lussier]

I am relatively new to using LaTeX through TM so I'm not sure if this  
is a common experience, but when I ask TM to typeset my LaTeX (cmd-R)  
the command runs for a very long time (i.e. a few minutes) even though  
the document isn't very long (25 pages) and only has a few medium  
sized images.

If anyone has had similar difficulties and can suggest things I can  
try or check that would be great.

Many thanks,

Dan
