After a few minutes of run with Sprinter 11 patch 9 against SAP GUI 7.20, SAP GUI 7.20 controls are displayed in different positions of the screen from those where they should appear. When this happen, SAP GUI hangs partially (it is not in "Not Responding" status but no actions can be performed) and Sprinter stops recording user actions against SAP GUI. No memory increase/general system performance decrease is observed when the problem occurs. The issue takes place exclusively with SAP GUI, other applications do not show it.
SAP GUI 7.20 does not have the minimum patch level necessary for Sprinter.
To fix this issue, the minimum SAP GUI 7.20 patch level needed to record and run tests with Sprinter is patch level 4. To work around this problem, please install SAP GUI 7.20 patch 4 or higher.
The same issue can occur for SAP GUI 6.40. For this version make sure to install SAP GUI 6.40 patch level 2 or later.
