Update: This is still happening, but now in the mousedown event of a grid on a pageframe. I haven't been able to reproduce in the IDE where I can trace it. It occurs intermittently in the live application, but somwewhat frequently. Any one have an enlightening explanation about this error? It sounds like a Zen Koan, but when is an object on a form not on a form?

Error number:       1938
Error message: Object is not contained in a FORM.
The error occurred in : dd.pageframe1.page3.grid1.MouseDown
Line #  :          0

>>>This worked, at least the error method does what it is supposed to now. The other issues remain. Re-constructing the combo box on the form did not help. Those 2 errors persist.

>>>>>See Thread# 1038518 , which helped with some of the occurences of these 2 errors. The referenced methods are not usually where any culprit lies, ex: the mousedown event was one place referenced, and it has no override code in it, for that form.

>>>>>Other issue: My error method from the project form class no longer closes the program after an error, as it was doing. In the code below, after creating an errorlog record, the 'close all' command gets run, but the QUIT fails to quit, which leads to a cascade of further errors, that have to be answered until you can be allowed to close the form.
