"a custom control callback raised an exception"

Hello all,

yes, there are several posts about this error message, but they are all pretty old (<2009) and the solutions didn't seem to work, so I'm starting a new thread.

I installed 2013sp1 last week and removed 8.5, 2010 and 2012 this morning. And now one of my projects won't compile. Other projects aren't impacted (I tested about 10 in two different workspaces).

When I compile, I get a popup box with "a custom control callback raised an exception" and it comes back as soon as I click it. I have to kill CVI. It's a project that compiled cleanly with CVI2012 (no warnings). I can open and save the UIR files with CVI2013, no problem. I also deleted the cws file, no change.

I generated a debug log (cleaned up a bit):

The last line gets duplicated every time I click the popup, so it's relevant.
