"Index was outside the bounds of the array" error out of nowhere

[Eugene]

Hello all,
I've been trying to figure this out for a few days now, and still have
no clue what's going on...
I have a few related tables in MS Access (Clients, Cars, Sales), and a
datagrid, binded to dataview.
Here's a catch - whenever I select a client, and then find a car which
belongs to this client, and click on empty space in datagrid (that is
in gray area below rows) - I get "Index was outside the bounds of the
array" error...
Works only in that order. Selecting the same car without finding
Client first works fine.
I even wrapped the Main in try-catch block - it's not being handled.
Drives me nuts.
Anyone have any suggestions ?
Below is the full error message I get (if it helps)
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.
