Cant advance my PBEM turn

[Embis]

Its possible I am missing something obvious here, if so I am sure someone will promptly put me right!

Playing a PBEM game of pacific war; I have some reinforcements arriving this turn and they need to come in on a hex occupied by some of my opponents troops, Obviously I cant bring them in, but neither can I finish my turn! Every time I try to advance the turn, the reinforcement dialogue pops up and invites me to place my unplaceable reinforcements. I suspect this is one for Rich Hamilton, but thought I would check with you guys first. Anyone else seen this?

I hope we can fix this because I suspect I am in the process of trouncing Steve Jones and I really dont want to lose that on a technicality!!
