Updating the UI while converting databases to V5

[Beatrix Willius]

1+

That worked in the gone times of Carbon. In certain situations I could tell the window with the progressbar to show immediately and then to update.

In Cocoa this doesn't work. Trying to force showing a window: crash. Update window directly: crash. Show a message box: crash. Instead I tell the progressbar window to show itself, which it does - sooner or later. Sometimes a sleepcurrentthread(100) seems to help, but not always. 

As soon as Valentina is doing something like reindexing the complete interface is locked down!

I haven't had time for the example, yet. Will try over Easter.
