If you select the "Details" tabs during installation, you will observe that the progress window will stop working, when the progress window has been filled up to its maximum window size.

Reproducible: Always

Steps to Reproduce:
1. Prepare for an installation
2. When the installation has started, switch to the "Details" tabs
3. Observe that the progress window works very nicely as long as the window maximum size has not been reached -- As soon as the maximum size has been reached, the progress is no longer shown, nor is it possible to use the scroll bar to see want is going on.
Actual Results:  
The progress window stops showing the current progress of the installation, just as the scroll bar cannot be used to move down in order to be able to see, what is currently going on.

Expected Results:  
The progress window should continue to show the most current progress of the installation process.
