Outter compatible to a Flt3 + Flt2 install?

Hi Fellas,I can't remember anymore about this. I did a new install of Flt3 with Flt2 today(actually I copied all 5 cd's to my hd first, install seemed to go much quicker). Will there be problems flying in either hi-res region if I generate the mega tiles?My feeble brain has 2 memories of this 1)I had at one time had an install of flt3,2 plus outter terrain and everything was fine, I was even able to flt plan from between either hi-res and OT.2) It wasn't o.k., I would cdt if I tried to fly out of SF hi-res + outer terrain packages icons would show up off the coast of Cal.Currently I also have Flt2 installed stand alone(my previous post).You all take care,JimB.
