after uploading our Enterprise Portal from 6.40 SP18 to 6.40 SP21 we have experienced a very extrange issue that didn't happen in our test environment.
In our WebDynpro applications, when the user presses a field associated with a Date attribute (fact that opens a Calendar when the user can choose a day) the Calendar that appears doesn't allow to change neither the month nor the year and the font of the letters is different.
Something similar happens with the DropDowns, the list that appears has a different font that the rest of the application and doesn't allows to scroll down.
Anybody has any idea of what could be happening?
Answers would be rewarded!
Thank you very much!
