Thanks, I'll try that if it happens again. &nbsp;Before I got your answer, I recreated the two forms from scratch, carefully layering things the right way the first time. &nbsp;I was able to copy from the original, so it only took about four hours.<br />
<br />
These are very complex forms, so I would add a few things, save, close and re-open to ensure all was OK before proceeding.<br />
<br />
I guess I had done something in the form designer that confused the issue, so a clean restructure appears to have eliminated the problems.<br />
<br />
Thanks again

I have encountered a problem in VS 2010/VB.Net.<br />
<br />
I open a project, and open a form file in the design mode. The tab above it has an asterisk indicating it needs to be saved, even though I haven't changed anything. I can edit it, save it, compile the .exe and all is fine. &nbsp;But if I try to close that tab, VS blows up.<br />
<br />
Once I restart VS, if I open the project again, the same thing happens.<br />
<br />
Is there a Visual Studio setting that might affect this?<br />
<br />
Of course, it doesn't happen on all form files, but on most.<br />
<br />
This just started about a week ago. &nbsp;I went back to old backups, and it happens on them now as well. &nbsp;Therefore, I believe Visual Studio is the culprit.<br />
<br />
Thanks for any suggestions.
