I have attached a file out of a simple program that demonstrates the problem. It is a window with two table widgets, each with four columns. The reorder column feature is set on and the drag/drop attributes are set.
Again, running the program in the development environment, works fine. After packaging, the reorder column feature works after a fashion. It is hard to grab the column header and the wrong header is grabbed.
I'm thinking the problem is not with the column reorder code (but it could be) as much as with some low level mouse event code
