Yep, that's right, the latest build of mGalaxy could not give the expected result with the search window.
This concern was quickly addressed. I will ask you to download the mGalaxy installer again and to proceed to a new install.
Simply keep a copy of your 'License.xml' file and 'Data' folder somewhere.
Uninstall, then install from the new installer.
Finally, put the 'License.xml' and 'Data' folder that you backed-up into the mGalaxy folder!
Really sorry for the inconvenience!
