The app I support is active on over 1500 users computers all using windows 10.  I have one user with a similarly configured computer that is having a problem I have not seen before.  When they run the app and it attempts to open its first "Response" window, the window displays, but the entry/edit fields are protected and the cursor shows an hour glass.  After a few seconds the window disappears and the app terminates (task manager shows the app as being unresponsive at this time).  I changed the window to "Main!" as a test and I do not get the problem.  There is a data window within the response window, but it does not do a retrieve.

Any ideas?
