Adobe Forms (SO10)texts not working properly anymore

Hi experts,

we recently did an upgrade at a customer and we have come across the folowing error.

We made some forms using Adobe Interactive Forms (SFP). We use SO10 texts to fill in the letters(the form gets filled in, then generates a letter using SO10).

What we have noticed is that since the upgrade, the SO10 text get random enters/line breaks. Even words are getting line-breaks in between.

This was all working without errors before the upgrade, so my guess is I need to look for some issue there. But after a day of looking and searching, i have yet to come across anything. I've alo found no posts simillar to my problem at SDN.

So if anyone has any idea, please help.

Much appreciated.
