>> If I put a breakpoint on "With thisform", and during the run, click the button, then the err. mess. occurs sort of at the same time as debug is invoked. A window (presumably debug) flashes on and off before I can see it, the error messag pops up. When I dismiss it (it only has OK or Help buttons), and open debug, the cursor is either on "With thisform" or sitting waiting to do ".lmCompileReport()"

Tell me about it! :-)
