I am working in a Visual Basic application, modifying existing projects and
code.  For the most part, the auto-indent seems to be going what it's
supposed to.  But occasionally, when I'm modifying or deleting code, the
auto-indent for surrounding code seems to get messed up.  Code is indented
one or more times when it shouldn't be.  

I have tried to remove the indentations manually, but when I move to another
line, the incorrect indentation reappears.  This seems to be random - for the
most part, the indentation is working correctly.

Has anyone seen this before, and have you been able to fix it?

Thanks!
Dave P.
