since this already came up a few times on IRC, here is a little note about freezes at startup of Geany with recent GTK/GLib runtime environments.
If you installed a GTK runtime environment which has GTK 2.12.x and GLib 2.16.x, Geany won't start. It freezes while starting, the process is still running in idle mode but you won't even see the main window. This is by some changes in GLib 2.16.x which require to build Geany differently. The next Windows build of Geany or the next release will contain these changes and will run again.
In the meantime, just install Geany from the full installer which contains a GTK runtime environment which is known to work with Geany.
