Error using Marine Recorder tree control to select biotope codes.
==================================================================

Error:
======
When trying to select a biotope code from the tree you may see:

The expression MouseMove you entered as the event property setting produced the following error. Object or class does not support the set of events.
	The expression may not result in the name of a macro, the name of a user-defined function, or [Event Procedure]
	There may have been an error evaluating the function, event or macro.

Cause:
======
This is caused by a Microsoft update breaking a shared component described here: http://support.microsoft.com/kb/2748410

Workaround:
===========
You can still use the filter and the drop down list to pick a biotope code

Fix:
====
As described in the MS KB article: http://support.microsoft.com/kb/2748410 a dll needs updating.

The dll is in the zip with this file for Access 2003 (the runtime Marine Recorder uses)

1) Take a copy of the original mscomctl.ocx  - check below for file location depending on 32/64 bit system(in case you need to reverse the change - zipping the file in situ is OK)

2) Unregister the file using either:
	If working on a 64-bit system, execute the following  command:
			Regsvr32 /u "C:\Windows\SysWOW64\MSCOMCTL.OCX"
    If working on a 32-bit system, execute this command instead:	
			Regsvr32 /u "C:\Windows\System32\MSCOMCTL.OCX"	

3) Copy in file to appropriate place:
	If working on a 64-bit system,
			"C:\Windows\SysWOW64\MSCOMCTL.OCX"
    If working on a 32-bit system, 	
			"C:\Windows\System32\MSCOMCTL.OCX"	

4) Register the new file using either:
	If working on a 64-bit system, execute the following  command:
			Regsvr32  "C:\Windows\SysWOW64\MSCOMCTL.OCX"
    If working on a 32-bit system, execute this command instead:	
			Regsvr32 "C:\Windows\System32\MSCOMCTL.OCX"
