re: Printing "Contact Sheets" from Thumbnails
The first quirk is a design thing, the second is really a bug. There is no print button - it took me a while to figure out that I had to highlight the list of image files in the first tab, right click, and select Print that way. Another would be the Print Preview function - if you use the Print Preview button on the interface it shows the sheet in Landscape; but if you choose Print then Preview, it is shown in Portrait. It actually printed in Portrait, which is fine.
Program exit would be another bug. When I right click and Exit, I get the exception error below. However, I can exit cleanly if I go to Task Manager/Processes and kill the process manually. The exception text is shown at the bottom.
I can live with both of these now that I figured them out. I will close the thread, thanks again!

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (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 computer
rather than be handled by this dialog box.
