Sorry, what do you mean when you say "more than one parent task"? Did you mean 
"more than one predecessor task" ?

And what do you mean when you say "IDs from the predecessors are dropped" ? I 
just've created a project in GP with task1, task2, task3, so that task1 and 
task2 are predecessors of task3, exported to MPX and imported back to GP (no MS 
Project ta hand) --both dependencies are there.

Hello again, Sorry for my missing words. 
i Mean dependencies with id's
i Open the mpx in ms Project 2010 and the dependencies are broken

May I ask you to create in MS Project a file with a task with to predecessors, 
export it to MPX and attach it here? If you additionally verify that MS Project 
imports that MPX file back normally, that would be just perfect.

OK here we are...
I used the latest RC of Gantt (RC3) and MS Project 2010.

The predecessors get lost again and durations converted from days to hours.

here the files i created in gantt:
http://dl.dropbox.com/u/79075/Gantt/test%20gantt.gan
http://dl.dropbox.com/u/79075/Gantt/test%20gantt.mpx

looks like this in gantt:

and this in msproject 2010:
http://dl.dropbox.com/u/79075/Gantt/test%20gantt%20in%20msproject%202010.JPG

and here are the msproject samples in different versions (sorry there is no 
*.mpx export. Only *.mpp and *.xml):

http://dl.dropbox.com/u/79075/Gantt/test%20msproject%202007.mpp
http://dl.dropbox.com/u/79075/Gantt/test%20msproject%202000-2003.mpp
http://dl.dropbox.com/u/79075/Gantt/test%20msproject%20xml.xml

are there any news to this issue?

The problem is that MPX file produced by GanttProject is syntactically correct. 
For some reasons, MSProject doesn't parse it correctly, so it appears to be 
Microsoft's bug. That's why I would like to see MPX file with two predecessors 
which MS Project opens correctly. I thought that MS Project itself could create 
such file but apparently it can't save MPX.

So, why don't you try to export to Microsoft XML from GanttProject? My 
experiments were successful, it opened with two predecessors in MS Project

I am closing it as "Wont Fix" since it seems to be a bug in MS Project and we 
hardly can do anything with it, and there is a workaround: use MS XML format. 
Please let me know if you find an example of MPX file with two predecessors 
which opens correctly in MS Project.
