Version:           1.2.0 (using KDE 3.5.0 Level "a" , SUSE 10.0 UNSUPPORTED)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.13-15-smp

Steps to reproduce:
1. Load KStars
2. Goto Settings > Configure KStars
3. Change any setting. For example, switch off the Hipparchos catalog.
4. Hit Apply or OK.

Actual Result:
The settings are not immediately applied. (The stars do not disappear.) They are applied only after a redraw is manually caused by the cursor keys or other input.

Expected Result:
The settings should be immediately applied. (The stars should disappear.) This is the meaning of "Apply" and implied meaning of "OK". A redraw should be implemented immediately when the "Apply" or "OK" button is pressed in the settings dialog.

Comment:
This bug should be simple enough to fix. Just call a redraw function when the Apply or OK button is pressed. (I am only now learning Qt programming else I would contribute this fix myself.)
