To Reproduce:
Open one or two folders at left panel
open one or two folders at right panel, make any folder active at right panel

Note: to exit from left panel, no problem, the error only happen when change to single panel mode from right panel

Confirmed.

Bug report sent.

P.S. if you tried to reproduce this and want your old config back, open "FreeCommander.ini" file and change "MainSplitterOrient=3" line to "MainSplitterOrient=0".
