I am having random problems with FM Pro11.0v3, whenever I try to print to the Brother HL-2140 it tells me I cannot continue to print because the printer cannot be found, it prints from other programs, but not from filemaker. It works fine and then it doesn't. I am running Windows 7 64 bit. I also get a message "Thunking Spooler from APIS has stopped working" on my Vista 64 bit computer. I have tried uninstalling and reinstalling the printer but that didn't help. I have 6 work stations and right now these are the only two I'm having problems with. I know you have issues with 64 bit, but there has to be an answer, none of my other programs have a problem.
