Several problems #124

Hi there,
Sardoj, your module designer is awesome but I have some problems...

1. The image field is not working. Actually it is not uploading any photos at all.
2. Cannot named a related list in Greek language. It shows only underscores at the right bar.
3. How can I insert a check box field? Cannot find it.
4. When I rename the fields or blocks, changes are not showing.
5. The biggest problem is when I want to edit an existed module. (e.g. contacts.) Let's say that I have create 5 fields via the standard module manager of vtiger. Everything works fine!!! But When I edit Contacts via module designer (e.g. add a related field) and save it, all the 5 fields that I have created are totally missing from the page! Login Into the phpmyadmin these 5 fields are there...
   I have no idea about programming and I dont know where to search for these problems.
   Any help would be appreciated.

Thanks at all!
Greetings from Greece!
