 :?: **What can I do with MySQL?**
-MySQL was used as the default database up to the version alpha 7. Since June 2005 it is replaced by the more simple SQLite. You can still use MySQL if required, for example to share the database across a local network.
+MySQL was used as the default database up to the version alpha 7. Since June 2005 it is replaced by the more simple SQLite. You can still use MySQL if required but it is now depreciated and will be removed after the release of version 4.2.
 The database is used to store the following data: asteroids and comets elements, object pictures and world locations.
 ===== Usage =====
+:?: **I need black colors as I can see in some screenshot here**
+The program use the system theme color, so change them to a dark theme.\\
+But there is some subtleties and you may need the following.
+  *On Linux: Use a dark Qt theme, for example Breeze-dark. When using a GNOME desktop you need to use qt5ct to set the theme, and set the environment variable QT_QPA_PLATFORMTHEME=qt5ct
+  *On macOS: Since macOS 10.14 you can set a dark theme in the preferences.
+  *On Windows:
+    *Open the Windows settings, search "night light", turn it on and adjust the color.
+    *Or download a compatible dark theme, for example [[ https://www.deviantart.com/eversins/art/GreyEveTheme-FINAL-Windows-10-High-Contrast-Theme-643504863| GreyEveTheme]]. Extract the zip and double click on the .theme file

 Yes, //Cartes du Ciel-SkyChart// V3.0 can use **[[http://indi.sourceforge.net/|INDI]]** to interface the telescope. Any telescope model supported by INDI must work with //Cartes du Ciel-SkyChart//.
 Also you can use the include interface for Meade/LX200 protocol or a simple encoder interface.\\

 No, the standard communication protocol for the V3 is TCP/IP for portability reasons.
-:?: **Why are the the fonts with my Linux version too small / too big?**
-There was a problem about Gtk1 font settings on Linux in the past. In the latest versions of Skychart, Gtk2 is used by default. There should not be such a problem now. If so, please report the bug to us.

-Yes - unofficially this has been tested against OS Version: 10.0.10240 N/A Build 10240 on 27-10-2015
+This is a bug with the current version of Qt.\\
+To re-open the program you have to right click on the dock icon, select "Show All Windows" and click on the small windows image.\\
+You can also uncheck "Minimize windows into application icon" in System Preferences / Dock.\\
+This bug is fixed since version 4.1.
-===== Common Problems =====
+:?: **The 64bit version of the program crash on startup**
+You need an AMD or Intel 64bit processor more recent than 2005 or 2006 that support the LAHF and SAHF instructions. Otherwise you must use the 32bit version.\\
+See: [[https://en.wikipedia.org/wiki/X86-64#Older_implementations]]
+:?: **On Linux, every character I type in the search box are doubled**
+This is a bug with some input method. The solution is to install the ibus-gtk package for your system and set ibus as your default input method.\\
+Or if it is not possible to change the default, run skychart with the following command:
+<code>GTK_IM_MODULE=ibus skychart</code>
 :?: **I've installed CdC V3.0 but program doesn't display stars or objects.**
