Anspress still conflicts with many plugins permalinks

I’m continuesly finding problems when Anspress is enabled, with various permalinks. Last week there was the theme’s paging (fixed in RC) and now several 404 from plugins. Contact forms and a couple of others.

Not sure why i get a 404 in plugin usage when Anspress is enabled. I think there is a global major problem in Anspress permalinks code, messing a lot of things.
