when ever I try and shut my Rev. A 12" PB, the lid will not click shut. I have to manually stick a paper clip in the latch on top to pop out the clip, then the book will shut. This happens 8/10 times. Small dog says it would cost 129 for the part then 4 hours of labor at $89 per hour, which is nearing $500 for a latch fix, nearly 1/2 of the total cost of the book in the first place. Are they crazy, or am I up the creek here? Any suggestions, or similar experiences? Thanks!
