I found this code lines on the Palm os Programming Bible:
ListType *list = GetObjectPtr(PopupList);
ControlType *popTrig = GetObjectPtr(PopupTrigger);
Char *label = CtlGetLabel(popTrig);
StrCopy(label, LstGetSelectionText(list,LstGetSelection(list)));
CtlSetLabel(popTrig, label);
this is supose to set the current selection on a PopupTrigger element.
It does this, but it also unables the next selections: when I press the popup
on my form,the rest of the elements don't apear anymore...

It could be that you are overwriting some memory locations
unintentionally. When you use the StrCopy command, you are writing a
new string onto the old label location, but if the new string is longer
than the ORIGINAL label was (probably set when you defined the popup
trigger in your resource file) then you will overwrite the end of the
original memory location, and start writing on top of other stuff.
Often, the list is defined right after the trigger, so you might be
overwriting the beginning of the list structure.
