[Exim] eximon queue update problem

Hi,

I've compiled and installed exim 3.31 on RedHat 7.1 and I appear to be
having a problem with my eximon.

The queue window doesn't clear before it lists the entries in the queue, so
the list keeps on growing.

I've tried it compiled with both the eximon.conf I edited and the stock
"EDITME" version and had the same results.

Has anyone else experienced the same thing? Or might know if I'd
inadvertently broken something?

Thanks,
Matt.
