Well with the recent push of 64bit Office and the problems that arise by the lack of the usual .ocx maybe its time for a step forward....how about Open Source the usual suspects like MsFlxGrd and the alike...its a fact that you have some brilliant controls over 20 years old that alive and kicking in 32bit but not in 64bit and A lot of developers are forced to get stucked in 32bit because they just work and they provide unparalled functionality ....so if you really want to push the 64bit and for any reason you can't develop the 64bit equivalents of these controls maybe you should leave it for someone else....
I am pretty sure that if this comes with a price bonus...64bit Access will be fully functional in a mater of months
