MP -Problem clicking on airfields ?

[242Sqn_Prof]

Does anyone know if there is a bug in Multi-Player (with the latest patch) where you select an Army and then try and click on an airfield but nothing happens. I'm reasonably sure I'm doing it correctly because twice out of hundreds of clicks it did work. I have windows 7 and have turned off the Areo graphics. I've read that this was happening before the patch as well. It does appear it's only happening to some people and I'm one of them I guess. Thanks.
