I've had similar experiences, and it's DEFINITELY a bug as far as I'm concerned. I will suggest that when you select an expression to copy it (or copy over it), try selecting ONLY by multiple-clicking. (Triple-click a function name to select it with all its arguments, for instance.) That way, the front-end grabs a selection it likes. That limits your options, of course. If you're about to do "surgery" on a complicated expression, copy it to a new cell and save the notebook first. When I want to add parentheses, I tend to select the expression I want them to enclose, click the exponentiation template from the BasicInput palette, and then delete the exponent if I don't need it. That usually puts parentheses around the expression. I'm sure there are other similar tricks and better ways to perform those, as well; I wish I knew them all.

(The expression is intended to collect text to be inserted into graphics using Text[] and Show[]. The real-life examples are three or four times as long.) Sometimes these work fine; sometimes for unknown reasons they get screwed up -- especially if I cut and paste the expression within the Module to move it or duplicate it. When this happens: 1) I get the error message Syntax::sntxb: Expression cannot begin with "<> K2 = <>ToString[K2//N]". 2) Some of the lines become indented by slightly different amounts before the "<>"'s. 3) The program is now totally unstoppable: Interrupt Evaluation or Abort Evaluation no longer stop the program, which will apparently Run forever. Only way out is to Quit the front end, then Quit the kernal, and restart the app. 3) Once you've reopened the notebook, laboriously doing a delete and then CR at the beginning of each line is the only way to restore functionality, Obviously I'll stop typing them this way and let Mathematica make the line breaks -- but this does seem like some kind of bug?
