I have an app that has, among other controls, a tabpanel on the only window. In one of the tabs is a listbox, several labels, and a few TextFields and a TextArea. The issue comes in when I launch an icon on the desktop while the tab is being displayed. What happens is the TextFields and TextArea outlines disappear. The contents of the fields remain, only the outlines of the control disappear. And only for the TextFields and TextArea.
The TextField outlines remain hidden until the mouse moves over the control, the outline of the TextArea doesn’t redraw with a mouse enter.
Clicking in the window to reactivate it redraws the controls properly if there is a refresh in the activate event.
The problem does not happen to text fields not on the tabpanel.
I guess my question is why does the outlines of the controls disappear when the window is deactivated and, if possible, how do I prevent it from happening?
The ones on the window proper stay properly displayed. And why does it only seem to happen when opening a different icon on the desktop. Simply selecting a different, already open application window does not how the problem.
Environment:
Windows 7 64bit
Xojo 2015r3.1 (and earlier, I tried it)
Puzzled.
