Hi, I am developeing a tool simmilar to Office Communicator using RTC Client api. While running the tool, as the login happens through RTC api, the Micorsoft Office Communicator running on my system automatically logs out. Is it that only one login can be done from a machine. Please let me know any links mentioning this. Also please let me know if there is any way to do simultaneous login using RTC as well as Office Communicator, so that My communicator will be running always irrespective what other tools, using RTC, are running.
