hi there
i was using orca in vista 32 bits and there was no problems
then, because i wanted to add some memory to my pc i changed the os to Vista Business 64bits
and i downloaded the latest version of orca 1.2.0.5
now after installation and restart when i run orca nothing happens
there's a process os orca*32 in processes in task manager after running, but nothing more
is it possible that orca is not compatible with my os ver?
and i have no problems in my work on firefox 3.5.3 or opera 10
tanx for your help

for what it's worth, orca's running fine here - vista home premium 64-bit. I'm not aware of any relevant differences between home premium and business...
