I've just purchase and upgraded to PB12.5.2. I'm running on Windows 8.
When testing the application I'm maintaining, if there is a bug in the code, say, 'invalid row/column', the test-run of the application either freezes or shuts down: no error message is given.
If I put breakpoints in the code and step through the problem area, when I get to the problem code-row, the step-through process stops at that row and, if I click to go past it, the screen dims and refreshes. The pointer remains at that point.
