SYMPTOMS
When running a 16-bit RUI application on a computer running Windows NT that is using the SNA Server 2.11 or SNA Workstation 2.11 RUI thunking DLL interface, the application may not be properly notified of asynchronous completion of an RUI call, causing the application to quit responding (hang).



CAUSE
The SNA Server LUA RUI and SLI thunking DLLs were not properly allocating and locking memory for verb control blocks, causing 16-bit RUI thunking calls to fail to complete.



RESOLUTION
An update to SNA Server and SNA Workstation 2.11 (newer than Service Pack 2) and SNA Server 3.0 are available to correct this problem.



STATUS
Microsoft has confirmed this to be a problem in SNA Server and SNA Workstation version 2.11 and SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack.
