Whenever I have a problem with explorer and it crashes

Are the crashes because of True Launch Bar?

Generally to save the toolbar position you need open toolbar and logoff/logon. Explorer saves its state on exit. But if you get the explorer crash on logoff then maybe Explorer don't save the state.

Also try one of these tips how to correctly exit Windows Explorer:
Windows XP
Select Start->Turn Off Computer. When Windows show the Turn Off Computer window press and hold down CTRL+SHIFT and press Cancel

Windows Vista
Open the Start menu, press and hold down CTRL+SHIFT and right-click the turn off button. Select Exit Explorer menu item.

The you can press CTRL+SHIFT+ESC to run the Task Manager and run the explorer.exe ( File->New Task (Run) )

Sometimes this helps to save the Windows Explorer state.
