    <p>Okay, it sounds like </p> <ol> <li>In the main window a user starts a long operation</li> <li>You display a progress modal window</li> <li>Operation completes you close the progress window</li> <li>Your main window doesn't display immediately. Instead something behind it shows through for a second or less.</li> <li>Your main window completes it's redraw operation and is 100% visible.</li> <li>This happens more often when you have applications such as Skype running.</li> </ol> <p>If that's the case there are many different possible causes. For example, your video drivers might have a bug in them causing delays in off screen compositing under certain conditions. </p> <p>The system itself might even be experiencing a blocking CPU operation at the moment. This is something that could be caused by the time it takes your code to close the dialog and go back to the main form. You might look to see if there is anything else you are doing between the time the progress closes and you return UI control back to the user.</p> <p>The system might simply be memory constrained and your operation causes a huge swap to disk. When the operation completes, windows might be notified that it needs to pull previously swapped memory from disk and shove it back into RAM, causing a delay.</p> <hr> <p>I'd run the app with <em>Nothing</em> else loaded but task manager or resource monitor and see what happens. If the problem no longer occurs, then look into adding more RAM to your machine and/or ignore it. </p> <p>If it's still occuring, and your memory usage leaves nearly nothing left then, again, add RAM or ignore.</p> <p>If it's still occuring but memory usage is low, investigate your code to see what you are doing between the closing of the dialog and release of control of the main window back to the user.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
