strange errors

I have an issue where my program is behaving badly when I promote it from Test to QA.
I have moved the programs/files up and down between these two environments multiple times with the same results.
Below is what is happening in the QA Environment.

I have program A(subfile) that calls program B(maintenance). Program B has 2 main screens depending on record from program A. Both screens allow you to press a command key to call program C.
When returning from program C to program B one of the screens has the data on the left hand side of the screen disappear. The other screen works fine.
Both screens have the same keys words set.
Also I have a command key that prompts for a value that gets a Permanent I/O error.

I have deleted the programs/files from the QA environment and recompiled from scratch. Same results. When all are in my Test library the programs work as expected.

I'm not sure where to look. Is there anything in the compile listings, DSPPGM, etc ; I can search to see if somehow there is a difference?


Any insight into what might be happening here?
