Hi,
Does it take Time when you press back or exit the transaction Launcher?
If this is the case then I think there might be the problem with your Session Time Out.
For this you need to go to TC ‘RZ11’ and need to increase the value of parameter ‘rdisp/plugin_auto_logout’.
Also check below Doc if there is any issue with the System Threshold Memory.
Hope it helps.
Thanks
Kumar
