When opening a database from a project and the Browse Data tab is the active tab, the message box:

"The database is currently busy: reading rows
Do you want to continue"

is displayed.

1. The loadProject function calls the fileOpen function to open the database, then continues processing.
2. fileOpen opens the database then tests if the current widget is the browser tab. If so, it calls populateTable, continues processing and returns to loadProject.
3. loadProject continues processing, then calls populateTable just before returning.
4. The call to populateTable from loadProject conflicts with the call from fileOpen causing waitForDbRelease to display the message that the db is busy.

The correction for this problem is to change fileOpen from

            if(ui->mainTab->currentWidget() == ui->browser) 
                populateTable();

to include a check if it had been called from loadProject before calling populateTable

            if( (ui->mainTab->currentWidget() == ui->browser)  && !openFromProject )
                populateTable();
