back window of swift charisma

Hello,

Just wondered if anyone else had had this problem. We went away for  NY and when we were setting up (in the rain!)  I noticed the rain was pouring in through the top of the back window. On closer inspection the screws  that screw into the van body were loose - all the screws were half out. We managed to screw them back in and make the van water tight, we took the van to the repair man on the way home and he said it may have been an attempted break in but was unable to say for sure. The van is store in a golds COSSA compound, (who have yet to get back to me regarding the concern re: breach of security). Has anyone else experienced the screws holding a window in place coming loose?
