SAM_DragCanAutoStarton table windows has recently started causing failures in row and column resizing. Instead of resizing the column or row, the table window seems to be processing double-clicks.
The problem happens to the app on my development box (whether in design mode or run-time), as well as the deployed app on pristine end-user machines.
I don't have any time to really dig into what's going on, but removing
SAM_CornerClickprocessing (which just returns TRUE when a row is selected, and returns FALSE otherwise) fixes things.
As far as I can tell, only one of two things could have caused this strange behavior:
- I may have recently added/changed some unrelated code somewhere that affects focus or active window, but I can't think of anything I could have done recently other than benign changes (the SAM_DragCanAutoStart processing has not been touched since first added years ago)
- Some recent Windows update might have done something ?
