problems with strings mixed into notebook cells

Since I cannot find any other reports, and I cannot offer a simple replication, I anticipate widespread disbelief of the following claim. Oh well .... I have a notebook. Some cells contain a dozen expressions. I started inserting some Print commands to help me identify the output. Mathematica occasionally (but pretty often) would then tell me that I'm missing parenthesis in a subsequent expression. (I think but am not certain that this usually happened with more than one Print command in a cell.) Removing the Print command (and its argument) removed the problem. So I stopped using such Print commands. But today I wanted some clues again, so I just inserted some strings (without Print commands). The same problem happened again: Mathematica stopped evaluating the subsequent statement, claiming it was missing a parenthesis. I changed the string to a comment (making no other changes) and the problem went away. Has anyone else seen this? Alan (Using version 8 on 64 bit Vista. )
