If you were expecting Adobe to issue patches for Captivate 5.5 for relatively minor issues like this one, I'm afraid you are bound to be disappointed. Cp 5.5 is now around three versions behind the times. Adobe's focus by now is on the latest builds.
I would recommend you download trial versions of the latest Cp and test to see if your issue has been resolved there. If not, THEN you might stand a chance of seeing something get fixed...in the next version, or the one after that.
