I am using filemaker go 12
I also need an advise, If I switch back to filemaker11, will my users be able to purchase fm11 to run the application say for the next year.
I am asking that because I was already suffering from the slowness before rm12 and now it might drive away my users from using this application at the same time that I am not making use of the other enhancements.
I don't have an iPad or iPhone, You may want to ask that question in the FM Go Forum (see tab at top of this screen). As far as I know, the methods used to connect to the hosted database have not changed.
I'm just a fellow user. FileMaker Inc.'s policies for selling copies of FileMaker 11 is not something I have any more knowledge about than you do.
OK thank you.
