Dejection in Rejection by Word!

As a routine I was saving a document file (MS Office Word 2007) after its preparation. After entering the name of the file, I clicked the Save tab. But the file was not saved and the Save As page was retained with the instruction to enter a competent file name! I repeated and tried all the means to save, but in vain. Dejected, I changed the christened name (a Blog post’s title) and found next that the file was saved! Luckily I didn’t use the ‘question mark’ this time – which I used earlier: yes, as a question mark was used in the name the file had been repeatedly rejected in saving it!
