A user have found a stupid error on last version of TGoogleMaps: if you try to inizialize TGoogleMaps 2 or more times (but sometimes also the first time) you have a javascript error because TGoogleMaps try to send javascript code before read html file from server.
I just have fixed this bug and uploaded the version 1.1.1 for WITH SOURCE edition, I also upload the new version of demo application.
This evening I will update to version 1.1.1 also WITHOUT SOURCE edition, until this eveining you will find also WITH SOURCE edition on my strore.
Thanks to Christian for bug report.
