Summary

When you close the Laserfiche Client, the LFSESSION.EXE process remains running. This may cause your Citrix session to hang or prevent your Citrix session from closing.

Cause

LFSESSION.EXE is a child process created by Laserfiche client applications to store repository authentication information. When you close the Laserfiche Client (LF.exe), it does not automatically end the LFSESSION.EXE process. This can cause your Citrix session to remain open in the background.

Workaround

Modify the following registry key to include special handling for LFSESSION.EXE:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI

Add or modify the following string value to include LFSESSION.EXE:

LogoffCheckSysModules
