Paul the problem is not to do with FTN95 or Clearwin as the simple C program below crashes when I try to move the window with pen or touch. So perhaps it is as you say a Microsoft problem, or a problem with the pen driver or a problem with SLINK
I have been unsuccessful in getting a trace back other than the one that showed ninput.dll.
I have reloaded windows 8.1 to no avail.
I have tried tracking the windows messages as they appear in the Windows Procedure - so for example when moving the window I would expect to see a WM_MOVE message. At the point I would expect to see the message the program crashes.
Here is the simple c program that crashes when trying to move the window.
It has no menu but the crash still occurs when the pen is in the Non-Client area of the window.
