BugSeeker supports a very handy feature called data tooltips or datatips which are basically tooltips that display the value of the identifier the mouse hovers over in the source viewer. The way datatips are implemented in BugSeeker is whatever identifier is located beneath the mouse cursor is sent to the expression evaluator which will attempt to evaluate that identifier in context of the current stack frame and if there is a value of that identifier, it is displayed in the datatip that will appear for a few seconds. What this means is that BugSeeker knows nothing about the structure or types of local variables you hover your mouse over. Thus, if you hover the mouse over a comment string that happens to include text that matches the name of an identifier than can be evaluated, BugSeeker will happily display a datatip for that comment text.
To disable data tooltips, uncheck the Enable data tooltips option in Tools | Options | Debug category.
Hint: if you hover the mouse over selection of text in the source viewer, BugSeeker will try to evaluate the selected text and display the expression's value if any.
