DDE server option hanging the application

Hi,

My application uses DDE to exchange the data between two Powerbuilder applications[GetRemote ()]. But recently we are facing the issue application not responding. We are uising StartServerDDE to establish the application as DDE server and GetRemote() function to exchange the data.

In our initial analysis we found the application get struck at the point of GetRemote() function call.  We are using windows 7 (32 bit & 64 bit) nad code is built in PowerBuilder 12.0.

Any help will be appreciated!

Thanks & Regards
