My mcd11.2a home copy (on XP) will just close - as if I clicked the x in the upper right corner - when I click on, or drag into the open mathcad window - some newer files (recent, but also mcd11.2a) created at work. No error messages, no warnings, no indication of something wrong; just closing of the app. Older files resident on my home pc open and behave normally. A few months ago, I migrated my office work from an XP to a win7 machine. I was lucky enough to be able to install mathcad 11 on it with no problems and have had no usage problems on the win7 system. This recent behavior is the first time I've moved files from the win7 pc to the home xp pc. Are these events related? Right now, I'm just scratching my head in bewilderment.
