The developers have been VERY helpful with support and that makes using this directory even better! They are continuously improving the component so it is not stagnate like a lot of the directories out there.
I would highly recommend this directory and JoomGalaxy!
1) Allways use the latest version, 1.1.0 is not latest version (1.1.1 is the latest)
2) I see no problem with markers and IE in 1.1.0, the same for 1.1.1:
3) I see no reporting about such problem in Phoca Forum?
Please if you have some problem which can be caused e.g. by your another extension on your site, etc., please try to describe it in Phoca Forum, so then it can be solved.
Thank you, Jan
