[sas belezy provencel]

Hello I upgrate to parallels 7 and I cannot choose the coherence mode anymore as i could before, it stays in grey. i am not at all a computer geek and also my parallel is in french, so if you have an easy way to do this please explain me !!
thank you so much

What you should try for sure - is to reinstall Parallels Tools. Go to Virtual Machine menu --> reinstall Parallels tools. If it does not help - use this kb www.kb.parallels.com/8969
