My vendor has written AcuCobol programs with GUI screens.  I install the software on the main Windows 2019 server and all is good.  I then publish the wrun32.exe program on my Remote Desktop collection and then download the rdp file to my local machine.  When I execute the .rdp session from my machine and then log into the software, I have window refresh issues on query screens. For example, I go to customer inquiry, search for a customer, then select customer.  The customer data is not displayed on the GUI screen until I take my mouse and literally move the customer inquiry screen just a bit.  Basically the data won't populate the screen until I force a refresh.  It seems once the refresh is done initially, it then refreshes normally upon subsequent queries until I close the window and reopen.  I have talked with the vendor and they don't know why this is happening.  They even updated the runtime to version 10.4.1 on the server today in hopes of solving the issue but it did not help.  Hopefully some of you out there might have RDP experience with Acocobol???  It does work fine on the server when NOT using RDP from a local machine so it definitely appears to be a remote desktop issue of some kind.  I can't expect my users to manually move the window each time that they enter a query screen!
