I've closed left scope occasionaly. Now program crashes during every start: "ldapadmin.exe has generated errors and will be closed by Windows".
Here's win 2k, sp4, ie60.
I tried to uninstall ldapadmin and then back install.
I tried to repair in such way:
Add/Remove Programs -> Softerra Ldap Administrator -> Change -> Repair
Windows's rebooted

So, I uninstalled it, manually removed any Ldap Administrator v3.0 entries from registry and installed it again.
Good luck, guys, in bugfixing
