ZOHO creator

Hi all,
I have been playing with zoho creator and some of the other applications in the ZHO suite, really wonderful and useable stuff, congratulations.
I have a couple of remarks:
1) When in a field, you don't seem to be able to use the "backspace" button to edit what you just typed, even the arrows don't seem to move the cursor.
2) You can't "TAB" from one field to the next. (both of these things work fine in this form for example)
3) Whenever I try to export data from a form to excel, i get error messages
4) It would be wonderful if the help files were a little more extensive. I want to develop a little application that incorporates a few different forms in one to one and one to many relaionship, and I am having trouble finding instructions on how to manage that. there is info on how to set it up, basically, but how to pull that all together in an application and how to create queries that extract specific information from the application, or reports is not described anywhere that I can find.
Warm regards,
Roland hanekroot
