HARRISBURG, Pa.—Pennsylvania State Police say a glitch in the state computer system that handles applications for concealed-weapon permits is fixed.

State police spokeswoman Maria Finn said the problem was resolved Thursday afternoon, after four days of intermittent breakdowns that delayed permits for people who applied for them during that period. The computer problem prevented county sheriffs from uploading photographs and printing the concealed-carry licenses.

Finn says thousands of people apply for the permits each week but that she didn't know how many were affected by the problem.

It didn't affect the separate computer system that is used to conduct instant background checks on most gun purchases in Pennsylvania.
