Chrome has it's own internal Flash that it uses rather than any installed version. you can set it to use the External instead. ( see here - http://lifehacker.com/5705588/how-to-get-the-flash-102-beta-working-in-google-chrome you just use the instructions there to disable the Chrome folder plugin) it is suspected - tho not confirmed - that if you run both the external flash (such as Poser or Firefox) plus Chromes internal at the same time, they can conflict.

personally I turned off Chromes internal long long ago...

as to Air which is what 64bit Pro uses, I don't know if Chrome affects that.
