Help Adjusting Door

[harrdawg54]

I just finished painting my truck and am trying to adjust the doors. I had no issues with the drivers side but when I tried to do the passengers side I adjusted the door to the opening then installed the striker on the cab....and the door stuck shut. I had to use a dremel to cut slots in the back of the bolts to be able to unscrew them to finally beat the door open. I changed out the striker because I didn't have this problem before I painted and now have the same problem. My question is why is it sticking and how do I fix it. Any help is appreciated.
